What the episode covers

The Supreme Court's 6-3 ruling in Louisiana v. Callais on April 29, 2026, gutted Section 2 of the Voting Rights Act — and within hours, Florida's legislature had already voted to redraw its congressional map. For voters in Florida, Tennessee, and more than a dozen other states, that sequence means the districts deciding their representation in Congress are being redrawn right now, with fewer legal tools available to stop maps drawn for partisan advantage.

Grant and Maya work through what Justice Alito's majority opinion actually changed about the Thornburg v. Gingles framework — and why Justice Kagan's dissent called Section 2 'all but a dead letter.' They trace how Rucho v. Common Cause (2019) and Callais together removed the two main federal checks on rigged maps, then catalog the on-the-ground consequences: DeSantis signing Florida's new map on May 4, Tennessee moving within eight days, and PBS analysis putting 14 additional Republican-leaning seats in play nationally.

  • Alito's majority quietly restored a discriminatory intent requirement that Congress had explicitly removed in 1982
  • Florida's new map targets four Democratic incumbents, potentially shifting the delegation from 20 to 24 Republican seats
  • The Purcell principle gives states a practical shield — maps signed quickly become nearly injunction-proof before November
  • California's Proposition 50 passed with 64 percent support as a direct counter-redistricting move

In the closing segment, Grant delivers a firm no check on redistricting oversight; Maya offers a reluctant partial check, pointing to the live Tennessee NAACP lawsuit as the last real test before November 2026.

Quick answers

Straight from the episode

The questions this one settles, without the listen.

What did the Supreme Court rule in Louisiana v. Callais?
On April 29, 2026, the Supreme Court ruled 6-3 that Louisiana's second majority-Black congressional district was an unconstitutional racial gerrymander. The central irony, as the episode explains, is that Louisiana drew the district specifically to comply with the Voting Rights Act — and Justice Alito's majority held that compliance itself was the violation.
How did the Callais ruling change the Voting Rights Act Section 2 framework?
Alito's majority quietly rewrote the three-part Gingles test by sliding an intent requirement back into the 'totality of circumstances' analysis — a requirement Congress had explicitly removed in 1982. The practical result, as Justice Kagan's dissent put it, is that Section 2 is now 'all but a dead letter': it exists on paper but no longer functions as an enforceable check on discriminatory maps.
What is the Purcell principle and why does it matter for redistricting challenges?
The Purcell principle holds that courts are reluctant to issue injunctions against election rules close to an election. States are exploiting this as an offensive strategy — signing new maps quickly so they become nearly injunction-proof before November. The episode cites the 2022 Georgia playbook as an early example of this tactic.
How many congressional seats could shift because of post-Callais redistricting?
PBS analysis cited in the episode puts 14 additional Republican-leaning seats in play nationally. Florida alone aims to shift its delegation from 20 to 24 GOP seats, putting Representatives Castor, Soto, Moskowitz, and Wasserman Schultz at risk. Tennessee's new map could eliminate Steve Cohen's Memphis district and potentially create a 9-0 Republican delegation there.
What is the combined effect of Rucho v. Common Cause and Callais on redistricting oversight?
Rucho declared federal courts out of partisan gerrymandering cases entirely — a justiciability ruling. Callais raised the Section 2 evidentiary bar so high it functions as a near-total block on racial discrimination claims. Together, they removed the two main federal checks on rigged maps: partisan gain is greenlit by Rucho, and the racial discrimination bar is raised by Callais — effectively two locks on the same door.
Is there any meaningful check left on gerrymandering after Callais?
Grant delivers a firm 'no check' verdict, citing the structural collapse of federal corrective mechanisms. Maya offers a reluctant 'partial check,' pointing to the live Tennessee NAACP lawsuit before a state three-judge panel and Purcell friction as imperfect constraints. California's Proposition 50, approved 64-36, could net Democrats up to five seats as a counter-gerrymander, but the broader norm protecting independent redistricting commissions has collapsed.

GrantWelcome to Power Check. I'm Grant.

MayaAnd I'm Maya. Okay, so the Supreme Court dropped a ruling six weeks ago that state legislators are already sprinting to use, and I don't think most people have fully clocked what happened.

GrantApril twenty ninth, Louisiana versus Callais, six to three; Justice Alito writes the majority,

MayaHmm.

GrantJustice Kagan writes the dissent, and her line is the one that's been rattling around in my head.

MayaSection two, all but a dead letter.

GrantThat's the dissent; and she's not wrong

MayaWow.

Grantabout the practical effect. The Voting Rights Act's main tool just got gutted.

MayaAnd Florida's legislator had already voted to redraw its map by the time the ruling was public. That's how fast this moved.

GrantDeSantis signed it May fourth; Tennessee signed a new map eight days after

MayaYeah.

GrantCallais dropped. The map scramble is very much on.

MayaSo today, we're pulling this apart layer by layer. The legal mechanics. What this actually means. Actually does to the Voting Rights Act.

GrantAnd how it connects to Rucho v. Common Cause from 2019, which already closed one door on federal courts.

MayaRight. Two rulings, two different doors, and we'll get into whether that framing even holds.

GrantI have some thoughts on that.

MayaI know you do. We also catalog where the redrawing is actually happening. Florida, Tennessee, what PBS analysis puts at 14 Republican-leaning seats nationally now in play. own play.

GrantAnd we close with our check or no check segment. Is redistricting oversight working? Short answer, you're not going to love it.

MayaOr maybe you will, depending on who you're rooting for. The cold open starts now.

GrantYeah, so April twenty ninth, the Supreme Court drops Louisiana versus Callais, six three, Justice Alito writing, and before the ink is dry, the Florida House and Senate both vote to approve a new congressional map. Same day,

Speaker 3Wow.

Grantsame hour.

MayaThat's not a coincidence. DeSantis had called the special session before the ruling even landed. They were ready.

GrantOh, they were warmed up.

MayaDryly.

GrantPre-loaded and the map they passed. has to put four Democratic incumbents directly in the crosshairs.

MayaFour?

GrantFour. Ballotpedia reported that HB 1-D passed 83-28 in the House, 21-17 in the Senate.

MayaHmm.

GrantThe whole thing done in a single afternoon.

MayaOkay, okay, okay. So let's talk about what the court actually did, because Democracy Docket called it an onslaught, and that word fits. The ruling itself came down 6-3, written by Alito, striking Louisiana's second majority black district. as an unconstitutional racial gerrymander.

GrantRight. And the majority's logic is the twist. Louisiana drew that district specifically to comply with the Voting Rights Act. Alito said the VRA didn't require it, so using race to draw it was unconstitutional. You followed the law, and that's the problem.

MayaComplying with the law is now the violation.

GrantThat's roughly where we are.

MayaAnd Kagan doesn't mince words in the dissent: she calls Section Two of the Voting Rights Act, and I'm quoting directly, "all but a dead letter.

GrantSCOTUSblog flagged that line immediately. She wrote, "The consequences are likely to be far reaching and grave: sixty-one years of civil rights law and the dissent is saying it's functionally gone.

MayaWithout striking it down.

GrantWithout formally striking it down, Section Two still exists on paper.

MayaHmm!

GrantI know—the math doesn't work, and everyone knows it.

MayaAnd Florida is just the first domino. NBC News reported states across the South – Louisiana, Tennessee, Georgia – all making moves on redistricting before November. The ruling dropped a green light, and people sprinted.

GrantWhich raises the question nobody in that courthouse seems to want to answer: If you can't use race to protect minority voters, and you can't challenge partisan maps either, what legal tool is actually left? So let's back up 30 seconds. Before Callais, how does Section 2 actually work? Because I think people hear Voting Rights Act and assume it's some kind of magic shield.

MayaRight, like it just prevents bad things.

GrantYeah, the reality is more mechanical than that. Since 1986, any redistricting challenge under Section 2 ran through a three-part test from a case called Thornburg v. Gingles. Minority group has to be large enough and compact enough to form a majority in a single district, they vote cohesively, and the white majority votes as a block to usually beat their preferred candidate.

MayaSo you're proving that the map is diluting actual votes, not just that it looks bad on paper.

GrantExactly. And critically, you did not have to prove anyone intent. Intended to discriminate, discriminatory effect was enough; that mattered enormously in practice.

MayaOkay, so what did Alito do to that?

GrantHe rewrote it.

Speaker 4I'm

GrantThree changes: one, plaintiff's sample maps have to satisfy all of a state's political goals, not just show a minority district is drawable; two, evidence of racial voting patterns has to rule out partisan explanations; and three, this is the one that really moves the goal posts: On the totality of circumstances you now need strong evidence of present day intentional discrimination.

MayaWait, hold on; he put intent back in?

GrantThrough the back door? The Brennan Center's analysis called it a rewrite that makes the claim practically impossible to prove.

MayaWow.

GrantHistorical discrimination? Alito says that gets much less weight now.

MayaSo the entire history that was the point of the VRA is suddenly less relevant?

GrantPer the majority, basically. And the NAACP Legal Defense Fund's position is that this guts Section 2 in practice without formally striking it down. Down! The statute still exists on paper.

MayaPlot twist: the law is still there, it just doesn't do anything.

GrantThe math on winning one of these cases just got a lot harder, and everybody knows it. Democracy Docket reported the ruling immediately triggered redistricting pushes in Louisiana, Tennessee, and Georgia.

MayaAll at once.

GrantAll at once. So you've got Section 2 effectively narrowed. But here's what the next question has to be: Was Section 2 even the last line of defense, or had another door already closed before Callais ever landed? ended. So, Rucho is where this story actually starts. Twenty nineteen, Roberts writes for a five four majority, partisan gerrymandering claims are political questions, federal courts out, done.

MayaLike, completely out?

GrantCompletely out. Roberts acknowledged gerrymandering may be incompatible with democratic principles and then said courts still can't touch it. Not their problem.

MayaThat is a sentence.

GrantIt really is. And the key word there. were there "justiciability." Rucho wasn't about intent, wasn't about impact; it was purely about whether federal courts have the authority to even hear the case. They said no.

MayaOkay, so that's door one closed. States can gerrymander for partisan gain, and federal courts won't intervene. But plaintiffs still had a second door: Section Two racial discrimination claims, which is exactly where Callais just slammed through. Lambed things shut.

GrantRight; and I want to push back slightly on calling it a 'clean one two sequence,' because the mechanisms are different. Rucho is a jurisdiction call, courts out entirely; Callais is about the standard of proof-it raises the bar so high that almost nobody clears it.

MayaHmm. Walk me through why that distinction matters going forward.

GrantBecause it means there's technically still a door,

MayaYeah.

Grantyou can still file a Section Two claim. Lame. The question is whether it's a real opening or just theater, and with the intent requirement sliding back in through totality of circumstances, practically speaking,

MayaTheater.

Grantthat's where the math lands, yeah.

MayaDemocracy Docket flagged the combined effect pretty bluntly:

GrantMm-hmm.

Maya"States can draw maps for pure partisan gain (Rucho greenlit that), and unless plaintiffs prove racial intent, minority voter protections won't stop them. Stop them!" Callais narrowed that—two different locks on the same door.

GrantAnd what makes it structurally significant not just politically is timing. Brookings noted that before Callais the Democratic mid-term outlook had actually been improving. Now that calculus shifts.

MayaAnd States didn't wait around to find out.

GrantNo. Louisiana, Tennessee, Georgia, redistricting pushes launched almost immediately, according to Democracy Docket. Docket.

MayaSo the legal architecture is done; the question now is what it looks like on the ground—actual governors, actual maps, actual seats.

GrantWhich is exactly where we're going—named states, real numbers, starting right now. Short pause.

MayaShort pause. So let's zoom in on the actual map scramble. Florida first. DeSantis signed his new map on May fourth, posted "Signed, sealed, and delivered" on social media. Very subtle.

GrantDryly. Real understated guy.

MayaThe Hill reported that map aims to take Florida's GOP delegation from twenty seats to twenty four, dropping Democrats from eight

Speaker 5to seven.

MayaFrom eight down to four. Castor and Tampa, district gone. Darren Soto in Central Florida, district gone. Moskowitz and Wasserman Schultz in South Florida, five Democratic-leaning districts compressed into three.

GrantNow, before we call that a clean four-seat pickup, the math has friction. Some of those redrawn districts aren't safe Republican turf. A veteran Florida GOP operative told NBC. See, this is going to put Republican members at risk-and they're right.

MayaSo it could backfire.

GrantIt could; but even a two seat net gain changes the House math significantly.

MayaThen Tennessee. Governor Bill Lee signed a new map May seventh, eight days after the Callais ruling. That's the speed we're talking about.

GrantEight days.

MayaNBC reported the map carves Steve Cohen's Memphis-based seat, the state's only Democratic-held. Held district into three pieces, spreading those voters across rural Republican districts stretching hundreds of miles east-Tennessee goes from eight one Republican to a potential nine zero sweep.

GrantAnd this is where the valuation lens actually matters: Tennessee was already eight one. You're converting one seat; Florida has more upside, or more risk, depending on how you model it. Not all redraws are created equal.

MayaPBS analysis found mid-decade redistricting has put 14 more House seats in play for Republicans and six more that could favor Democrats, and that's not even counting pending moves in Alabama, Louisiana and South Carolina.

GrantThe Purcell principle is the practical chokehold here. Federal courts resist changing election rules close to an election, which means the Callais era redraws may be shielded from injunctions. simply by being done quickly enough.

MayaSo speed is actually the legal strategy.

GrantBasically, get it done before the court clock runs out. The best defense against the judicial block is a signed map and a filing deadline that's already passed.

MayaWhich raises the uncomfortable question, if courts can't touch it before November and Congress has zero incentive to respond, what mechanism actually catches this? That's exactly what we need to look at.

GrantSo if no federal mechanism stops this before November, what actually can?

MayaRight. Congress is the obvious first answer. Theoretically, they could pass race-neutral redistricting standards.

GrantThey won't. Republicans control the chamber, and Callais just handed them the map-drawing advantage. You don't legislate away your own weapon.

MayaYeah, yeah, that tracks. So then it falls to state courts.

GrantMaybe, but only in states that have independent redistricting commissions. or strong fair elections language in their state constitution. Louisiana, Tennessee, Florida—none of them have that.

MayaSo the states where the redrawing is actually happening are exactly the states without those guardrails.

GrantFunny how that works.

MayaIncredible.

GrantAnd here's the counter-move Democrats made. California voters approved Proposition 50, Newsom's plan, which could net Democrats up to five seats. Virginia tried a similar play, but their Supreme Court blocked it on procedural grounds.

MayaOkay, so walk me through that. California actually passed this?

Grant64% voted yes. New maps through 2030. Then they go back to the Independent Commission.

MayaSo both parties are now drawing partisan maps, and CFR analysts are flagging that the whole dynamic just accelerates polarization regardless of who's holding the pen.

GrantWhich is the deeper problem. The court's ruling didn't just help Republicans in the South, it dissolved the norm that kept independent commissions politically defensible. California's response proves that.

MayaSo the oversight vacuum isn't just about stopping Republican gerrymanders. It's about the collapse.

Grantof the principal.

MayaExactly. And Congress can't fill that vacuum. It has no incentive. State courts can only intervene where the constitutional language already exists. The places being redrawn right now, that language isn't there.

GrantSo the check is the absence of a check.

MayaThat's about where I land, yeah, which sets up a pretty uncomfortable verdict heading into our final segment.

GrantAnd both of us have to answer whether the oversight mechanisms are are actually working, and I'm not sure either of us is going to like what we have to say.

MayaThe math on that one is not great. All right-check or no check, let's call it.

Speaker 3Yeah, I've been dragging this part.

MayaI'll go first-no check." The structural case is pretty clear at this point. Rucho took federal courts out of partisan gerrymandering entirely; Callais raised the Section Two bar high enough that racial challenges are functionally a dead end. Congress won't move-both corrective mechanisms are either shut off or too slow for November. November.

GrantI hear you, but I won't go full no check. I'd say partial check, and barely.

MayaWhat's holding you there?

Speaker 4Hmm.

GrantTennessee, actually. The NAACP filed suit the day the map was signed. A three-judge state court panel is now actively hearing the case.

MayaRight, but both sides are citing Purcell in opposite directions. Tennessee is arguing the map can't be blocked this close to the election. While the NAACP is arguing it shouldn't have been implemented in the first place

GrantAnd NBC News flagged something that makes this worse: the Callais majority didn't even mention Purcell when it greenlit the redistricting wave. Justice Jackson had to call that out in dissent.

MayaSo the court invented a rule about election eve interference then quietly set it aside for these cases right

GrantConsistency, very on brand.

MayaYeah; look, Purcell as a friction point, I'll give you that, it's real friction; but Balls and Strikes legal coverage made the point that Republican states have figured out how to time these signings precisely to weaponize Purcell as a shield rather than a constraint.

GrantWhich is what Georgia did in twenty twenty two: Kemp waited, challenges got stayed past the election, that's the playbook now.

MayaSo when I say no check, I don't mean there's zero resistance- I mean no check that lands before November.

GrantThat's probably right. Okay, so the state to actually watch?

MayaTennessee. The three-judge panel is the only live case with a real timeline question still open. If that court blocks the map, you get a concrete test of whether state courts can outrun Purcell. If it doesn't,

GrantThen the playbook wins and we know exactly what 2028 looks like.

Mayayou either see it coming or you don't. And right now. The map says we're seeing it. All right-that's our episode. If one thing stuck with me today, it's that Florida had already voted to redraw its map the same day Callais dropped. Same day, same hour.

GrantThat timing is not a coincidence, and Kagan's line, Section two rendered all but a dead letter, that's going to be quoted in voting rights cases for a long time.

MayaThe through line here is structural: Rucho closed one door, Callais closed another. The oversight mechanisms we assumed were in place, they were thinner than advertised.

GrantTennessee is the one to watch now. That NAACP case is live, and the Purcell clock is ticking.

MayaWatch the calendar.

GrantLiterally.

MayaIf PowerCheck helped you see how this actually works, not the headlines, the mechanics, share this one. One person who'd care.
