Florida's Supreme Court declined to touch the 24R-4D map on 10 June and the House qualifying deadline sealed it on 13 June, banking the Republican redistricting harvest into Cook's baseline. With the wave holding flat at D+6.6, the decisive 2026 fight has migrated to a handful of end-of-term court rulings that freeze the rulebook before a vote.
Maps are locked faster than courts can move; the appellate clock, not the trial floor, is the remaining 2026 variable.
The Florida Supreme Court declined to touch the Republican-drawn congressional map on 10 June, and three days later the candidate qualifying deadline sealed it before any appeal could reach the merits.
Florida's Supreme Court voted 6-1 on 10 June to defer the Fair Districts challenge to a lower court, leaving the 24R-4D congressional map untouched. The candidate qualifying deadline closed on 13 June, locking the map before any further appeal could land.
All six justices appointed by Governor Ron DeSantis declined to examine his own map. Cook Political Report's 9 June baseline now shows Democrats favoured in 206 seats versus 211 for Republicans, with the Florida map locked into those figures.
The Supreme Court is expected to rule by the end of June in NRSC v. FEC, a Republican challenge that could let party committees spend without limit hand-in-hand with their own candidates.
United StatesThe Supreme Court is expected to rule by end of June on whether Federal Election Campaign Act caps on party-to-candidate coordinated spending are constitutional. The case, argued on 9 December 2025, pits the National Republican Senatorial Committee against the Federal Election Commission.
Removing the caps would let party committees spend without limit alongside campaigns. That would dissolve the firewall forcing the Senate Leadership Fund to run its $342 million operation separately.
The Justice Department moved on 2 June to dismiss Common Cause v. DOJ, the suit defending its national voter-database programme, while pressing six appeals to scale a single winning ruling across many states.
The Department of Justice (DOJ) filed a motion on 2 June to dismiss its own Common Cause voter-database case. The case defended the SAVE (Safeguarding American Voter Eligibility) programme. Eight of the DOJ's 31 voter-data suits have been dismissed; six are on appeal.
At least 16 states have already handed over complete voter files. The DOJ abandoned the district-court fights it kept losing and is pursuing appellate wins that could bind many states at once.
Cook Political Report moved the Iowa Senate race toward Democrats on 3 June, and its Senate editor named the cause directly: the Iran War's effect on fuel and fertiliser prices for Iowa farmers.
United StatesCook Political Report moved Iowa's Senate race from Likely Republican to Lean Republican on 3 June. Analyst Jessica Taylor named the Iran War's fuel and fertiliser price impact on Iowa farmers as the direct cause. Josh Turek won the Democratic primary on 2 June with 63%.
A Gulf price shock hits Iowa farm households through two channels: fertiliser is a natural-gas derivative, and diesel powers the planting season. Turek faces Republican incumbent Ashley Hinson in November.
The Alaska Division of Elections notified a same-name challenger to Senator Dan Sullivan of ineligibility on 12 June, calling the identical-name filing a voter-confusion risk in his race against Mary Peltola.
Alaska's Division of Elections notified a retired teacher named Dan Sullivan on 12 June that he was ineligible for the Senate ballot. He filed as a Republican, creating an identical name and party label to incumbent Senator Dan Sullivan. The incumbent faces Democrat Mary Peltola in November.
Republican groups alleged the challenger donated to Democrats. Election lawyer Scott Kendall called removal extreme and proposed a middle-initial ballot label instead.
Sideways to up, depending on the NRSC v. FEC ruling expected before 30 June 2026. The map is now fixed at 206 Democratic to 211 Republican with 18 toss-ups in Cook's 9 June baseline; the trajectory variable is whether coordination caps of $61,800 to $3.7M per race fall before November. A ruling for the NRSC would immediately shift committee resources from the Senate Leadership Fund's $342 million parallel model into direct candidate coordination in Iowa, Montana, Ohio, Georgia, and North Carolina. The DOJ voter-data programme's appellate migration means election-infrastructure escalation now runs on the 9th Circuit's schedule rather than the administration's: 6 appeals are active, and a circuit split would force SCOTUS review. Iowa's 3 June Cook move on Iran-war fertiliser prices introduces a cross-topic variable that neither the map lock nor the coordination ruling resolves.
