Nine states will vote on new House districts on Nov. 3. ABC News says Republicans could net up to nine seats if every map works as designed, and that a good Democratic year could cut that. Missouri is not on the list: on Friday, Sept. 25, the Supreme Court kept its 2022 map in place for this election. Missouri voters decide on the new Republican map in November, for 2028. Trump's mid-decade push began in Texas, whose map was enacted Aug. 29, 2025.

Low
Alabama is among the states using a new House map that favors Republicans.
Alabama is absent from the Eighth Circuit's list of states that redrew. The only support is a redistricting tracker's note about June 2, 2026 stays in Allen v. Milligan/Singleton/Caster. No source states that Alabama will use a new Republican-favoring map in November.
Low
Republicans could net up to 9 House seats from redistricting if every map works as designed.
This is the desk's own unattributed ceiling. The sources disagree: the Midterm Project tracker estimated net ~+8 in May, and that figure included Missouri +1, which is now blocked. Cook's tracker estimates ~4 seats. The Hill's state-by-state gains do not sum to 9. No source gives a +9 figure.
Low
The Supreme Court's ruling ended Trump's mid-decade redistricting push, and the House maps are now final.
This is an unsourced sweeping and causal claim. Legal Newsline reports the Prop 50 merits case continues under Callais. Ballotpedia shows Missouri's HB 1 could still take effect via Proposition A in November. The Eighth Circuit notes Maryland, Mississippi and New York had begun redraws. The Sept. 25

Trump started the mid-decade redistricting push about 440 days ago (around mid-July 2025).
This is consistent with Texas's July 2025 redraw (Texas Tribune, July 31, 2025 draft map), but the 440-day figure is the desk's own calculation. No source dates the start of the push.
Medium
Every new map favors Republicans except California's and Utah's.
Multiple sources support Republican gains in several states: The Hill (Texas 5, NC 1, Ohio 2), the Midterm Project (Florida +4, Louisiana +1 est.), and Tennessee ('up to two'). California's Prop 50 yields Democrats +5 (The Hill), and Utah uses a court-drawn map (Democracy Docket, Utah Politics). Ala
