New Mexico voters head to the polls Tuesday for a Senate primary that, on paper, looks like a formality for incumbent Democrat Ben Ray Luján. The first-term senator faces only one primary challenger, and no Republican officially filed to run against him. Instead, Larry Marker is mounting a write-in campaign for the GOP nomination.
Luján, a former House Democratic leadership figure, is seeking a second term representing a state that has trended reliably blue in federal elections. His primary opponent is a relatively unknown figure who has not mounted a significant campaign. The lack of a contested Republican primary means the party's standard-bearer will be determined by write-in votes—a rare and difficult path to the general election.
The dynamics in New Mexico mirror broader trends in other states holding primaries Tuesday. In Iowa, the GOP primary battle to succeed Governor Kim Reynolds is heating up as polls open, with multiple candidates vying for the nomination in a competitive race. Meanwhile, New Mexico's House primaries are setting the stage for November battles, with several open seats attracting crowded fields.
Luján's campaign has focused on his record in Washington, including work on infrastructure, health care, and environmental issues. He has emphasized his role in securing federal funding for New Mexico projects and his support for the Biden administration's agenda. The senator has also highlighted his efforts to address the ongoing Epstein probe, which has ramped up locally with subpoenas targeting banks, the FBI, and a research institute.
On the Republican side, Larry Marker's write-in effort faces steep odds. Write-in candidates rarely succeed in securing a party nomination, and Marker has not reported significant fundraising or organizational support. If he fails to win enough write-in votes, the GOP could be left without a nominee for the Senate seat—a scenario that would effectively hand Luján reelection.
The lack of a serious Republican challenge underscores the state's political shift. New Mexico has not elected a Republican to the Senate since 2002, and Democrats hold all three of its House seats. However, down-ballot races remain competitive, with gubernatorial and House primaries drawing more attention. In the governor's race, Deb Haaland leads in the Democratic primary, while the GOP field is still taking shape.
Polls close at 9 p.m. ET, and Decision Desk HQ will provide live results. The outcome of the Senate primary is unlikely to surprise, but the write-in tally could offer hints about GOP enthusiasm heading into the general election. For now, Luján appears poised to cruise to renomination and set his sights on a second term.
