New Mexico General Election

Democratic · Incumbent since 2013

Martin Heinrich has represented New Mexico in the U.S. Senate since 2013. He previously served two terms in the U.S. House. An engineer by training and an avid outdoorsman, he sits on the Senate Intelligence and Energy and Natural Resources committees and has made clean energy and public lands conservation central to his agenda.

Democratic

Deb Haaland served as U.S. Secretary of the Interior from 2021 to 2025, becoming the first Native American to serve in a presidential cabinet. A member of the Pueblo of Laguna, she represented New Mexico's 1st Congressional District from 2019 to 2021. She is running for Governor of New Mexico as Governor Michelle Lujan Grisham is term-limited, leading the Democratic primary. She would be New Mexico's first Native American governor.

Republican

Gregg Hull served as Mayor of Rio Rancho, New Mexico — the state's second-largest city — from 2012 to 2022. He is the leading Republican candidate for governor in 2026 as Governor Michelle Lujan Grisham is term-limited. A businessman and community leader from Sandoval County, he built a reputation as a pragmatic administrator in Rio Rancho and is positioning himself as a results-focused alternative to what he describes as the Democratic establishment's management of New Mexico.
