DOJ Backs California GOP Bid to Block Prop. 50 Mid‑Decade House Map as Unconstitutional Racial Gerrymander
The U.S. Department of Justice has filed a Supreme Court brief siding with California Republicans and asking the court to block Proposition 50’s mid‑decade congressional map, arguing at least one district (CA‑13) was drawn on the basis of race to boost Latino voting power and that the map is therefore an unconstitutional racial gerrymander. The move follows a 2–1 federal panel ruling that upheld the voter‑approved Prop 50 map as a partisan (not racial) gerrymander—authorizing its use while litigation continues—and sets up an appeal to the Supreme Court as candidates prepare to file for 2026 races.
📌 Key Facts
- California voters approved Proposition 50 by about 64% in a Nov. 4 special election; the measure enacted new congressional maps meant to flip five Republican‑held seats to Democrats.
- A three‑judge federal panel in the Central District of California (2–1) rejected Republican and DOJ requests for an injunction, finding the plan was a partisan gerrymander but concluding plaintiffs failed to prove race predominated, so the new map may be used while litigation continues.
- Judge Josephine Staton’s majority opinion described Prop 50 as “exactly what it was billed as: a political gerrymander designed to flip five Republican‑held seats,” while Judge Kenneth Lee dissented, arguing at least one district was drawn based on race to curry favor with Latino voters.
- The U.S. Department of Justice (Solicitor General John Sauer) filed at the U.S. Supreme Court urging it to block California’s map, intervening on behalf of the state GOP and arguing District 13 (Central Valley) and the wider plan are unconstitutional racial gerrymanders that used race, not mere partisanship, to draw lines.
- DOJ and Republican challengers point to public statements by map consultant Paul Mitchell about boosting Latino voting power in District 13 as evidence that race predominated; defenders of Prop 50 say challengers have not met the stringent legal burden to prove racial predominance.
- California Republicans filed an emergency application asking the Supreme Court to enjoin Prop 50 and revert the state to the 2021 Citizens Redistricting Commission map; they sought an immediate response because 2026 House candidate filing under the new map was set to begin Feb. 9 (with the state’s response deadline reported as Jan. 29).
- The dispute is part of a broader mid‑decade redistricting wave — driven in part by pro‑redistricting pressure from former President Trump and recent Supreme Court orders (including a December decision allowing Texas’s partisan map to stand) — with several other states (e.g., Texas, Missouri, North Carolina, Ohio, Utah, Virginia) also experiencing contested or revised maps.
- Political reactions split predictably: Gov. Gavin Newsom said Prop 50 was meant to counter GOP mid‑decade rigging and called challenges a weak attempt to silence voters, while California GOP Chair Corrin Rankin called the map a pernicious, unconstitutional use of race and vowed to press the appeal to the Supreme Court.

- Gov. Gavin Newsom’s quote frames the ruling as Republicans’ 'weak attempt to silence voters' failing, while California GOP Chair Corrin Rankin vows to appeal to the Supreme Court and cites the dissent as better reflecting their legal view.

Federal court clears California’s new House map boosting Democrats ahead of 2026 midterms

- Fox reports Republicans are expected to appeal the ruling to the U.S. Supreme Court, signaling likely next steps in the litigation.

Court upholds Prop 50, allowing California to use its redrawn congressional maps
New information:
- A three‑judge federal panel in the Central District of California upheld Proposition 50, allowing California to use its newly redrawn congressional maps for the 2026–2030 cycles.

- Republican plaintiffs relied heavily on statements by consultant Paul Mitchell about bolstering Latino voting power in the 13th District; he did not testify despite GOP efforts to put him on the stand.
- The court’s reasoning leans on the Supreme Court’s recent decision letting Texas’s partisan map stand, including Justice Alito’s concurrence that both Texas and California were acting out of "partisan advantage pure and simple."
