Redistricting under Proposition 50, approved by voters in November 2025, transformed California's 3rd Congressional District from a lightly Republican seat—where Trump won by under four points—to a solidly Democratic one favoring Kamala Harris by 10 points, prompting incumbent Rep. Kevin Kiley to forgo reelection in February 2026 and seek another district. Rep. Ami Bera (D), a physician and former Sacramento County official with $1.9 million cash on hand as of late March, leads a crowded Democratic primary field ahead of the June 2 nonpartisan top-two contest, while Republican challengers like Christine Bish and Robb Tucker lag in fundraising. Unanimous Solid Democratic ratings from Cook Political Report, Inside Elections, and Sabato's Crystal Ball underpin trader consensus at over 90% for Democrats, though a GOP primary upset, Bera scandal, or midterm national wave could narrow the path.
