Voter registration administered by County Clerks in each of NM's 33 counties. Bernalillo County (Albuquerque), Santa Fe County, and Doña Ana County (Las Cruces) have the most resources. Rural counties (Harding, De Baca, Catron, Guadalupe, etc.) have very limited election office resources. Contact your specific county Clerk for local early voting sites and hours.
