Los Alamos County Candidate Filing Day for 2026 Primary Is March 10

Prospective candidates for county and local offices in Los Alamos County must submit declarations of candidacy and nominating petitions to the Los Alamos County Clerk between 9 a.m. and 5 p.m. on Tuesday, March 10, 2026, the statewide schedule confirms. LaDailyPost lists the March 10 county-clerk filings as covering "state representatives, one state senator, district judges, metropolitan court judges, magistrate judges, and public education commissioners," and specifies that "declarations of candidacy and filing fees or, in lieu thereof, pauper statements for all other elective county offices, shall be filed with the county clerk of the county in which the candidate resides, on Tuesday, March 10, 2026, between the hours of 9:00 a.m. and 5:00 p.m."

Statewide and congressional candidates already used the separate Secretary of State filing day on Tuesday, February 3, 2026, from 9 a.m. to 5 p.m., where "declarations of candidacy by pre-primary convention designation and nominating petitions for the office of United States Representative, Governor, Lieutenant Governor, Secretary of State, Attorney General, State Auditor, State Treasurer, Commissioner of Public Lands, and one judge of the Court of Appeals, shall be filed with the Secretary of State on Tuesday, February 3, 2026, between the hours of 9:00 a.m. and 5:00 p.m.," LaDailyPost states. The Secretary of State's candidate portal shows filings with timestamps on 2/3/2026, including entries for Lieutenant Governor and Commissioner of Public Lands that list contact details and status codes.

The Secretary of State campaign portal entries captured on February 3 include Harold James Pope, Jr. filing for Lieutenant Governor with a timestamp of 2/3/2026 1:00:26 PM, listed address 10460 Calle Leon NW, Albuquerque, NM 87114, email harold@popefornm.com and phone (505) 289-1087; Maggie Toulouse Oliver filing for Lieutenant Governor with a 2/3/2026 10:42:42 AM timestamp, address 4231 Vuelta Colorada, Santa Fe, NM 87507-7291, mailing PO Box 473, Albuquerque NM 87103, email maggieforlg@gmail.com and phone (505) 270-4079; Matthew McQueen filing for Commissioner of Public Lands at 2/3/2026 12:37:56 PM with address 38 Avenida Vieja, Lamy NM 87540, email mcqueenfornm@gmail.com and phone (505) 490-1989; and Jonas Moya filing for Commissioner of Public Lands at 2/3/2026 1:59:52 PM with address 1316 Valle Ln NW, Albuquerque NM 87107-2768, email info@jonasmoya.com and phone (505) 803-4955. Each portal row in the excerpt displays the codes "99 | Qualified | SW | False" or "99 | Qualified | SW | True" adjacent to timestamps; the portal text does not define those codes.

Campaign finance reporting deadlines tied to the primary are set on the Secretary of State site and require candidates to file multiple reports: the First Primary Report is due April 13, 2026, covering activity from October 7, 2025, through April 6, 2026; the Second Primary Report is due May 11, 2026, covering April 7, 2026, through May 4, 2026; the Third Primary Report is due May 28, 2026, covering May 5, 2026, through May 26, 2026; and the Fourth Primary Report is due July 2, 2026, covering May 27, 2026, through June 27, 2026.

Party and write-in deadlines intersect with the March 10 filings: LaDailyPost notes "No state convention for designating Primary Election candidates shall be held later than Sunday, March 8, 2026," and that "Certificates of Designation of Primary Election candidates shall be submitted by political parties to the Secretary of State no later than the first Tuesday succeeding the state convention between the hours of 9:00 a.m. and 5:00 p.m." LaDailyPost also sets a separate write-in declaration day: "Declarations of intent to be a write-in candidate for state representatives, one state senator, district judges, one district attorney, and public education commissioners shall be filed with the county clerk of the county in which the candidate resides, on Tuesday, March 17, 2026, between the hours of 9:00 a.m. and 5:00 p.m."

The filing schedule for New Mexico is anchored in statute. The Secretary of State guidance and the National Conference of State Legislatures table both reference N.M. Stat. Ann. § 1-8-26 and list the open-close windows as Feb. 3, 2026, 9 a.m. to 5 p.m. for statewide and congressional office and March 10, 2026, 9 a.m. to 5 p.m. for all other offices. Los Alamos candidates preparing to run in the June 2026 primary should plan filings according to these dates and the Secretary of State campaign finance schedule.
