Incumbent Democrat Sam Liccardo secured the top spot in California's June 2, 2026, top-two primary for the 16th Congressional District with roughly 75 percent of the vote, advancing alongside Republican Peter Soule, who edged out fellow Republican Kevin Johnson for second place. The district's results reflect Liccardo's strong incumbency advantage in a solidly Democratic seat following recent redistricting. California's nonpartisan primary system sends the two highest vote-getters to the November general election regardless of party, so trader focus now centers on final certification and any remaining ballot counting. No further primary events remain on the calendar that could alter these outcomes.
