Midterm Primaries 2026 Results and Key Takeaways

What This is

• A major 2026 primary night across several states produced unsettled marquee races and clearer results that are reshaping November matchups.
• In California’s top-two primary for governor, early returns had Republican Steve Hilton and Democrat Xavier Becerra narrowly leading in a race still too close to call as ballots continued to be counted.
• California’s governor primary was unusually expensive, with heavy advertising—much of it financed by billionaire Tom Steyer—helping define the contest.
• Several California local and down-ballot contests were also on the ballot under the top-two system, including Los Angeles mayor and numerous city, county, and legislative races where outcomes can shift as mail ballots are processed.
• Zach Lahn, a businessman and farmer, defeated a Trump-backed establishment candidate Randy Feenstra to win the Republican nomination for governor in Iowa on Tuesday
• In California congressional primaries, establishment Democrats generally fared better than prominent progressive challengers in several high-profile races, with debates over Israel and outside pro-Israel spending featuring in the contests.
• In New Jersey, Sen. Cory Booker was unopposed for the Democratic Senate nomination while Republicans competed for their party’s Senate nod, alongside multiple contested House and local primaries with results continuing as mail ballots arrive.
• Iowa’s primaries produced notable outcomes in statewide contests and are being treated by both parties as central to the fight for control of Congress.

Why This Matters

• Primary results determine which candidates and coalitions get a realistic path to power in November, often narrowing choices in ways that do not mirror general-election electorates.
• California’s top-two system can produce unexpected matchups, including the possibility that one party is shut out, shaping governance in the nation’s largest state.
• Large-scale outside spending tests how much donors and super PACs can steer nominations, which affects representation and public trust in elections.
• Trump’s continued sway over GOP nominations influences how Republican officials govern and campaign, and it can shift national policy debates even before the general election.
