The California Republican Party, Assemblyman David Tangipa and 18 California voters filed a federal lawsuit early Wednesday to challenge Prop 50, alleging it unconstitutionally gerrymanders districts in violation of the 14th and 15th Amendments.

Here’s how all 58 California counties voted on Prop 50, with around 75% of the vote in: Alameda - Yes, 79.9%. No, 20.1%. Alpine - Yes, 64.6%. No, 35.4%. Amador - Yes, 34.8%. No, 65.2% .

Assembly Member David Tangipa, 18 California voters and the California Republican Party are arguing in a federal lawsuit that Prop 50 violates the Constitution.

Proposition 50, a ballot measure about redrawing the state’s congressional districts, was crafted by Democrats in response to Trump urging Texas and other GOP-majority states to modify their congressional maps to favor Republicans, a move that was designed to maintain Republican control of the U.S. House of Representatives.

California voters approved Proposition 50 on Tuesday, Nov. 4, in a statewide special election that was announced less than three months prior. And in about a year, Californians will be back at the polls.

Proposition 50, backed by Gov. Gavin Newsom and the state’s Democratic Legislature, asked voters to replace the state’s independently drawn congressional districts with new maps
