4 major election results: NJ, Va. state races, NYC elects democratic socialist Mamdani, Calif. passes Prop 50

4. California voters approve Proposition 50 

Billed as an emergency measure to respond to mid-decade redistricting in Texas and elsewhere, Proposition 50 asked voters in California to set aside the congressional map adopted by the state’s Redistricting Commission and replace it with a map explicitly designed to benefit Democrats. 

California voters overwhelmingly approved Proposition 50. With 77% of the vote reporting, unofficial results show Proposition 50 passing with 64.4% of the vote. The new map is expected to have drastic implications for California’s congressional delegation. 

Currently, Democrats hold 43 of California’s 52 seats in the U.S. House of Representatives. The new map turns three districts currently represented by Republicans into seats that backed Kamala Harris for president by double digits in the 2024 presidential election: California’s 1st Congressional District, California’s 3rd Congressional District and California’s 41st Congressional District. 

California’s 48th Congressional District, which backed Republican President Donald Trump by double digits in the 2024 presidential election, will transform into a seat that supported Harris by 4 percentage points. California’s 22nd Congressional District will see Trump’s margin of victory drop from 6 percentage points to 2 percentage points. The map is likely to increase Democrats’ number of seats in the state to at least 46 and possibly 48 in a good year for the party.
