California Voters Approve Prop 50, Clearing Way for Legislature-Drawn House Map Through 2030

Decision desks projected a win that moves mapmaking from the independent commission to lawmakers through the next three cycles.

Overview

  • Major news decision desks, including AP, CNN and NBC, projected Proposition 50’s passage as polls closed, with official counts continuing under California’s mail-ballot timeline.
  • Proposition 50 replaces the commission’s congressional maps for the 2026, 2028 and 2030 elections, with the independent commission resuming its role after the 2030 census; the first primaries under the new lines are set for June 2, 2026.
  • The new map is expected to make up to five Republican-held seats more favorable to Democrats, with districts represented by Doug LaMalfa, Kevin Kiley, David Valadao, Ken Calvert and Darrell Issa among the most affected.
  • Gov. Gavin Newsom led a nationalized campaign framing the move as a counter to President Trump-backed mid‑decade redistricting in Texas, while opponents including Arnold Schwarzenegger and Rep. Kevin Kiley argued it undermines California’s independent safeguards.
  • Supporters outspent opponents by well over $100 million, and opposition figures said they had no immediate plans to sue even as future legal challenges remain possible.
