Los Alamos Democrats urge broad turnout as New Mexico opens primaries

Los Alamos voters who have never joined a party now have a new path into the June 2 primary, and county election officials say the shift could widen turnout in races that often hinge on a few hundred ballots.

The change comes from Senate Bill 16, signed into law April 7, 2025, as Chapter 54. It makes New Mexico’s 2026 primary the first to use a semi-open system, allowing voters registered as unaffiliated, or with a minor party, to request a Democratic or Republican ballot without changing their registration. Reform groups say the law opens primaries to more than 330,000 independent voters statewide, about a quarter of the electorate.

In Los Alamos County, the rules are straightforward: registered Democrats and Republicans vote in their party’s primary as usual, while unaffiliated voters can choose a major-party ballot. After May 5, voters cannot change party registration for this election, making the county clerk’s deadline a key cutoff for anyone still deciding how to participate.

That practical detail is why the Democratic Party of Los Alamos County is urging broad turnout rather than only speaking to party regulars. The county’s own election calendar shows how quickly the window is moving. Primary candidate filing was March 10, write-in filing was March 17, early voting begins May 5 at the Los Alamos Municipal Building, expanded early voting starts May 16 at both the Municipal Building and White Rock Town Hall, and the absentee ballot request deadline is May 19. Early voting ends May 30, and Election Day is June 2.

Same-day voter registration begins May 5 in Los Alamos County, and the New Mexico Secretary of State says it is available at county clerks’ offices, Election Day polling places, and participating early-voting locations. For residents who may have ignored primaries in the past, that means the process is no longer limited to people already locked into a party label.

The broader effect could be felt in local races and down-ballot contests where turnout is often low and every new voter matters. Local civic groups have already moved to explain the change. The League of Women Voters of Los Alamos published a 2026 primary voter guide and held a candidate forum April 30, underscoring that independents and Decline-to-State voters can now choose a ballot rather than sit out.

For a county where election margins can be narrow, the new system gives more neighbors a direct say in who advances to the June 2 primary, and it makes the next few days especially important for anyone still deciding how to vote.
