Voters in California on Tuesday are projected to approve a ballot measure to redraw the state's congressional maps, which could give Democrats a new five-seat edge in the House of Representatives.

Under the new rules, California will move forward with a redrawing of electoral districts only after GOP-led states do so first. Its changes would remain in force until elections in 2030.

In August, Lawmakers in California approved a bill that stipulated if voters approved the new maps, they would be used for the 2026 midterms.
