Incumbent Rep. Mike Thompson (D) commands overwhelming trader consensus at near-certainty to advance from California's top-two primary on June 2, 2026, alongside Democratic challenger Eric Jones, whose implied probability exceeds 90%, driven by their fundraising dominance—over $3 million each raised by late March, far outpacing six fragmented Republican contenders. Thompson's April 26 campaign relaunch emphasized bipartisanship, economic relief for the agriculture-heavy district, and criticism of congressional gridlock amid a partial DHS shutdown, reinforcing his entrenched moderate appeal in the redrawn, Solid Democratic-leaning seat. Republican vote-splitting in the nonpartisan primary favors a Democrat-Democrat general election matchup, per historical patterns since 2016.
