Republicans file lawsuit challenging California’s redistricting measure

California Republicans sued in federal court to halt Proposition 50, a newly approved redistricting plan that shifts map‑drawing to the legislature and could net Democrats up to five U.S. House seats. The complaint, brought by Assembly member David Tangipa, 18 voters and the state party, argues the maps unconstitutionally boost Latino voting power; plaintiffs seek an injunction. Democrats say the maps will stand. A PPIC analysis found racial representation largely unchanged. The measure passed decisively, 64% to 36% with 75% counted, amid national fights over gerrymandering and a pending Supreme Court case.
