6/3/2026, 11:14:25 PM
Core Primary Outcomes
On Tuesday night, primaries in California, Iowa, Montana, New Jersey, New Mexico and South Dakota chose party nominees for Senate, House and governor races. Republicans selected Rep. Ashley Hinson (Iowa), Sen. Mike Rounds (South Dakota), write-in Larry Marker (New Mexico) and Kurt Alme (Montana) for the Senate; the New Jersey Senate race remains uncalled and California has no Senate contest. Rep. Tom Kean Jr. secured the Republican nomination for New Jersey’s 7th congressional district. In gubernatorial contests, Democrat Deb Haaland won New Mexico’s primary, Democrat Rob Sand ran unopposed in Iowa, and Republican races in New Mexico and Iowa are too close to call. Gov. Kim Reynolds will not seek a third term in Iowa; California’s gubernatorial and mayoral primaries remain pending.
Background and Context
The primaries determine each party’s slate for the November 2024 general election. President Donald Trump endorsed Hinson in Iowa, Alme in Montana, and Kean in New Jersey. The outcomes set the field for Senate, House and state executive contests.
Key Republican Nominees
- Ashley Hinson – Iowa U.S. Representative; Trump-endorsed Senate candidate.
- Mike Rounds – Incumbent Republican senator from South Dakota, seeking re-election.
- Larry Marker – Write-in candidate who secured New Mexico’s Republican Senate nomination.
- Kurt Alme – Montana Senate hopeful endorsed by Trump.
- Tom Kean Jr. – New Jersey Representative, Trump-endorsed nominee for the 7th congressional district.
- Zach Lahn & Randy Feenstra – Republican contenders for Iowa’s governor nomination, reported neck-and-neck.
- Kim Reynolds – Iowa Republican governor, announced she will not pursue a third term.
Data and Statistics
Six states held primaries on the same night. Four Republican Senate nominees were decided (Iowa, South Dakota, New Mexico, Montana). One Republican House nominee (New Jersey). Two Democratic gubernatorial nominees (New Mexico, Iowa). Two Republican gubernatorial contests remain unresolved. President Trump endorsed three Republican candidates: Hinson, Alme, and Kean.
Implications for Upcoming General Election
The four Republican Senate nominees will face Democratic opponents in November, while the New Jersey Senate race remains undecided. Democratic nominees secured the New Mexico and Iowa gubernatorial primaries; Republican contests in those states are still unresolved. President Trump’s endorsements of Hinson, Alme and Kean were noted in the primary coverage.
Conflicting Reports and Gaps
The New Jersey Senate primary has not been called by the Associated Press. The Republican race for New Mexico governor is reported as too close to call. California’s pending gubernatorial and mayoral primary results remain undecided.
What’s Next
The Associated Press has not yet called the New Jersey Senate primary, and California’s gubernatorial and mayoral primary results remain pending. These outstanding outcomes are expected to be finalized in the coming weeks, completing the slate of candidates for the November 2024 ballot.
