What to Know
- Prop 50 was the only question before voters in Tuesday’s California special election.
- The measure asked the state’s 23 million registered voters whether they authorize temporary changes to congressional district maps approved by state lawmakers.
- Congressional district maps are usually redrawn once a decade after each census and by an independent voter-approved redistricting commission in California.
- Prop 50 is a response led by Gov. Gavin Newsom and Democrats to redistricting in Texas that came at the urging of President Trump in an effort to gain Republican seats in the U.S. House.
- Prop 50 opens a path to flip up to five of 435 U.S. House seats in favor of Democrats.
Californians were projected to overwhelmingly approve a congressional redistricting measure that was the only question on the ballot in the November special election.
“Yes” votes in support of Prop 50 held a 64% to 36% lead early Wednesday morning, a day after Election Day in California where statewide voter turnout was estimated at 35 percent. More than 7 million ballots had already been cast by mail and other voting options a day before Election Day.

It shows broad support for the measure on the coast and in Southern California, including in Los Angeles, Orange, San Bernardino, Riverside and Ventura counties.
In Los Angeles County, “Yes” votes were at 74%. Voter turnout in the state’s most populous county was 34 percent with nearly 2 million of more than 5.8 million registered voters casting ballots.
In Orange County, “Yes” votes were at 54.6% and “No” votes were at 45 percent with turnout at 39 percent.
“Generally speaking, odd-year elections tend to have much lower turnout,” said political analyst Dan Schnur. “First of all voters think, I just voted in a presidential election. Why do I have to vote again? And, second, ballot initiatives, particularly ballot issues as arcane and difficult to understand as redistricting, are not the kind of topics that are going to draw very large turnouts.
“But Gavin Newsom and his allies recast this initiative, not about issues about drawing legislative or congressional districts, but rather as a referendum on Donald Trump. It provoked an extraordinarily large turnout.”
The measure had little support in Northern California. “No” votes were at 79% percent in Lassen County and 78% in neighboring Modoc County in extreme northeastern California.
About Prop 50
Prop 50, named for the 50 states and the only question on ballot in the Tuesday statewide special election, was placed before the California’s 23 million registered voters as a counter to redistricting in Texas at the urging of President Trump that gives more seats to Republicans. The California measure, placed on the ballot by Gov. Gavin Newsom and the California Legislature, was a yes-or-no question that asked voters whether they authorize temporary changes to congressional district maps already approved by state lawmakers.
The changes could flip as many as five of 435 U.S. House seats in favor of Democrats.
The new congressional district maps approved by lawmakers in August would be used for the next three election cycles. After the 2030 U.S. Census, California’s independent redistricting commission would resume drawing the maps.

The next election for all U.S. House seats is 2026. Republicans have a slim 219-213 margin with three vacancies.
Voting districts are typically redrawn just once a decade after each census, but a national battle erupted over partisan gerrymandering this year in Texas when the Republican-controlled state adopted a new map in August that could flip five Democratic-leaning U.S. House seats. California responded in an effort led by Gov. Newsom. Missouri and North Carolina both adopted new maps and other states may soon follow.
California Democrats already hold 43 of the state’s 52 congressional seats. That number could jump to 48, if Prop 50 is approved and voters favor the Democratic candidates in those redrawn districts.
There are 10.3 million registered Democrats and 5.8 million registered Republicans in California, according to the Secretary of State. About 5.2 million voters were not registered with any party.
