Cibola County's electorate, shaped by a majority-Native American and Hispanic population centered around Grants and Acoma Pueblo, has shifted from reliably Democratic to one of the closer rural contests in the state over the past two cycles.
The county's recent history is a story of close margins. The Democratic margin reached thirty points in 2008; the Republican margin reached six points in 1984. Most other elections have been decided by single-digit points.
Cibola County's demographics — a population of 26,845, a 30% non-Hispanic-white share, a median household income of $50,759 — situate the county close to national averages on several dimensions. The county's voting pattern over the last decade is most similar to that of Big Horn County and Guadalupe County.
