California farmers and the state Farm Bureau are speaking out against Prop 50, warning it could dilute rural influence as Democrats seek to redraw congressional lines.

David Tangipa and the California Republican Party allege the new congressional map approved by voters violates the US Constitution.

California voters passed a ballot measure that could flip as many as five congressional seats to Democrats from Republicans, handing Governor Gavin Newsom a major political victory in his fight against President Donald Trump.

California voters passed Proposition 50 on Tuesday, in a major win for Governor Gavin Newsom and the Democrats.

Ken Calvert, who's been in Congress since 1993, said Wednesday that he plans to run in a district currently represented by Republican Rep. Young Kim.

Proposition 50, recently approved by California voters, allows temporary changes to the state's congressional district maps ahead of the 2026 midterm elections.

After President Trump asked Texas to remap districts to favor Republicans, California Gov. Gavin Newsom proposed Prop. 50. The measure would redraw California's map to favor Democrats and could flip up to five GOP House of Representative seats.

The aggressive gerrymander could help Democrats flip as many as five House seats next year. While that could neutralize new maps in Texas, Republicans are redrawing more district lines elsewhere.
