Democrats bested Republicans in California’s senatorial primary and most of the state’s 52 congressional contests on Super Tuesday.
Republicans, though outnumbered two-to-one in registered voters, managed to hold their ground by winning several congressional primaries that the Democratic National Committee (DNC) had targeted to flip in 2024.
In California’s open or “jungle” primary system, the top two finishers in each race—regardless of party—advance to the general election. That sets up a head-to-head rematch between the leading contenders in November.
Senate
Democrat congressman Adam Schiff defeated Republican Steve Garvey in the Senate primary, claiming 38 percent of the vote to Mr. Garvey’s 28 percent.November’s election will mark the first time in three election cycles that a Republican candidate has advanced to the general election.
Democrat congresswoman Katie Porter placed third with 15 percent. Democrat congresswoman Barbara Lee garnered 7 percent.
The March 5 election was unusual in that voters had the opportunity to vote for a senator twice, once in the primary election for a full, six-year Senate term and once in a special election to fill the remainder of the late Sen. Dianne Feinstein’s term. Ms. Feinstein, a Democrat, held the seat from 1993 until her death last September.
District 22
Incumbent Republican David Valadao appears poised to win in District 22, one of eight California seats the DNC hopes to flip in 2024.Mr. Valadao was several percentage points ahead of Democrat Rudy Salas late on March 5, setting up a November rematch between the two.
