RivCo Voters Support Proposition 50

As Proposition 50 Gained Support, Trump Fumed

RIVERSIDE COUNTY — A majority of Riverside County voters joined the rest of California on Tuesday to approve Proposition 50, the statewide congressional redistricting measure.

President Donald Trump fumed on Tuesday’s election night results, firing off a cryptic four-word message on Truth Social after a series of bruising defeats for Republicans across the map: “…AND SO IT BEGINS!”

The post came at 11:34 p.m. ET, less than an hour after California handed Democrats another structural advantage when voters in the state overwhelmingly backed Proposition 50, a redistricting overhaul that could shift multiple GOP seats next year., according to Mediaite.

With all Riverside County precincts reporting, 238,494 ballots, or 56.9%, were cast in favor of the measure, compared to 180,956, or 43.1%, against, according to election tallies from the California Secretary of State.

Election results will change, however, throughout the ballot-counting canvass period as vote-by-mail ballots, provisional ballots (including conditional voter registration provisional ballots), and other ballots are tallied.

Proposition 50 will establish new congressional district maps for the 2026, 2028 and 2030 elections. Democrats currently hold a 43-9 advantage in the state’s U.S. House delegation, but Prop. 50 is expected to shake up five of the nine Republican-held congressional districts.

The GOP congressmen in those at-risk areas — Reps. Ken Calvert (Corona), Darrell Issa (Vista), Kevin Kiley (Rocklin), David Valadao (Bakersfield) and Doug LaMalfa (Richvale) — will likely experience a drop-off of right-leaning voters and left-leaning voters boosted in their respective districts in a shift that would make it likely a Democratic candidate would prevail in each race.

Issa issued an unyielding statement, saying: “I’m not going anywhere. I’ll continue to represent the people of California regardless of their party or where they live.”

Calvert said Gov. Gavin Newsom engineered a “power grab” while housing costs, gas prices and taxes continue to strain family budgets. “I am determined to keep fighting for the families I represent,” he said in an email.

The measure, otherwise known as Congressional Redistricting or the Election Rigging Response Act, was spearheaded by Newsom. In August, he signed the legislative package that gave Californians a voice as to whether they wanted to push back against what Democrats characterize as President Donald Trump’s power grab in Texas and other Republican-led states.

With the 2026 midterm elections just a year away, the redrawing of congressional maps to favor Republicans is a Trump strategy to maintain GOP control of the U.S. House of Representatives.
