It’s Tuesday, Nov. 4: This is the final day to cast ballots in the special election on Proposition 50, the statewide congressional redistricting proposal.

More than 140 official ballot drop boxes will be open from 7 a.m. to 8 p.m., according to the San Diego County Registrar of Voters.

Locations of local vote centers and drop boxes are available here.

Voters will be asked whether to approve the redrawing of California’s congressional district lines in an effort to create more Democratic seats in the House — an effort Gov. Gavin Newsom says will offset similar moves in Texas designed to create more Republican seats.

Proposition 50, dubbed by supporters as “The Election Rigging Response Act,” would establish new congressional district maps for the 2026, 2028 and 2030 elections.

An analysis by the election news website Ballotpedia said it would shift five Republican-held congressional districts toward Democrats.

Democrats hold a 43-9 advantage in the state’s House delegation.

Opponents say Proposition 50 “creates one of the most extreme partisan gerrymanders in modern American history” and is a “threat to democracy and fair elections in California,” according to the campaign against the measure.

But backers of the measure say it “draws fair maps that represent California’s diverse communities and ensure our voices aren’t silenced by Republican gerrymandering in other states.”

San Diego County officials released an update Tuesday morning reminding voters that the counting does not end election night, and that mail and provisional ballots still need to be processed.

After election night, the next batch of unofficial results for the county is scheduled to be released by 6 p.m. on Thursday, Nov. 6, Friday, Nov. 7 and Monday, Nov. 10.
