California voters sent a strong anti-Donald Trump message on Tuesday by passing Proposition 50, another big win for Democrats during the 2025 off-year election that helps the party in the nationwide redistricting frenzy that will help decide who controls the U.S. House in the final two years of the Republican president's second term. Prop. 50 is a constitutional amendment pushed by Democratic Gov. Gavin Newsom that would allow the nation's most populous state to temporarily stop using a nonpartisan commission to draw congressional district boundaries. Instead, California will use lines drawn by Democratic state lawmakers to increase the seats they hold in Congress.
