Several U.S. primaries held Tuesday leave major outcomes still to be decided, with Democrats aiming to challenge Republicans in November general elections. In California, the crowded governor’s primary remains unresolved under the state’s nonpartisan top-two format, where only the top two finishers advance. The Los Angeles mayoral nonpartisan primary shows Karen Bass leading; she would still need to secure a strong share of the vote to avoid an uncertain general-election matchup. Multiple congressional contests in California also feature nonpartisan primaries that effectively determine the likely general-election opponents.

In Iowa, Democrats won key nominations for open U.S. Senate and House races. Josh Turek, an Iowa state representative, wins the Democratic nomination for the open U.S. Senate seat and is set to face Ashley Hinson, who has been endorsed by Donald Trump and is the Republican nominee. Iowa also sees Zach Lahn win the Republican gubernatorial nomination, setting up a contest against Democrat Rob Sand.

New Mexico’s Democratic gubernatorial nomination goes to Deb Haaland, while New Jersey’s Democratic nominations include Rebecca Bennett for the 7th congressional district and Adam Hamawy for the 12th congressional district, with general-election matchups still determined by the opposing nominees.
