California's gubernatorial primary remains too close to call with hundreds of thousands of ballots still uncounted. Billionaire Tom Steyer trails Trump-backed Steve Hilton and Democrat Xavier Becerra in partial results, though mail-in ballots could shift the outcome. The unusual field includes a former Fox News host and a former Biden official competing in November's nonpartisan runoff.

President Trump's endorsement machine hit a wall in Iowa, where Republicans nominated first-time candidate Zach Lahn over his choice, Representative Randy Feenstra. This marks a rare rejection of Trump's influence after his endorsements toppled incumbents in Louisiana, Kentucky, and Texas. The stumble raises questions about whether Republican voters are pushing back against establishment picks.

Los Angeles Mayor Karen Bass failed to secure 50% of the vote, forcing a runoff against either reality TV star Spencer Pratt or progressive councilwoman Nithya Raman. Meanwhile, New Jersey Representative Thomas Kean Jr. remains missing from public view nearly three months, with retired Navy pilot Rebecca Bennett winning the Democratic nomination for his seat.

Democratic factions both claimed victories: Josh Turek's Senate win in Iowa and progressive Sam Forstag's Montana House primary showed momentum for different wings. These results suggest November's general election will test both parties' ability to unify their competing coalitions.
