What is Prop 50?

California’s Proposition 50, also known as the "Election Rigging Response Act," is a countermeasure against mid-cycle partisan redistricting efforts in Texas and other states. If approved by voters, Proposition 50 would allow California to adopt a temporary congressional district map, drawn by the state legislature, from 2026 to 2030. In 2031, the once-per-decade redistricting process would take place as usual, based on the latest Census data.

If you are a California voter, you have the opportunity to vote directly to support or oppose Proposition 50 in a special election this year.

A ‘Yes’ vote on Prop 50 means… allowing California to adopt a new, temporary congressional map designed to offset gerrymandered maps in other states.

A ‘No’ vote on Prop 50 means… keeping the current congressional map in place until redistricting in 2031.
