California voters will go to the polls on Tuesday to weigh in on Proposition 50, a redistricting ballot measure that is part of a larger national push to see which party controls the House of Representatives during President Donald Trump’s last two years in office.

Proposition 50 would adopt a map passed by the state legislature in August that would redraw congressional district lines in favor of Democrats for the 2026, 2028, and 2030 elections, overriding a map created by California’s independent redistricting commission to prevent election gerrymandering.
