Proposition 50, the ballot measure to redraw the state’s congressional district maps, was passed by California voters and Santa Barbara County residents alike in Tuesday’s special election.

Early results show the temporary redistricting was approved by 64.4% of county residents, with 35.13% voting against it. State voters approved the measure with 63.8% of residents in favor, according to semi-official election night results.

As of Tuesday night’s count, 100,133 Santa Barbara County residents cast a vote in the special election, according to the Elections Office. That represents a 39.9% turnout for the county’s 250,857 registered voters.

Most of the votes were from mail-in ballots, which amounted to 88,863 returned ballots. Another 11,270 residents showed up at the polls to vote.

Statewide election night results show the proposition passing with 63.8% of the vote in favor.

The approved ballot measure will temporarily change California congressional district maps in a way intended to favor Democrats. The move is a response to other states, including Texas and Missouri, doing midcycle redistricting to favor Republicans and potentially add Republican representatives to Congress in the 2026 midterms.

These new California maps will be in effect until 2030, the year of the next redistricting cycle.

Proposition 50 was the only item on the ballot for the Tuesday special statewide election.
