County History:


Since New Mexico's statehood to the early 1940s Rio Arriba county was a traditional republican county. That would later change as the county would change to a democratic stronghold from the 1960s to present day. The last Republican Presidential candidate to carry the county was Dwight D. Eisenhower in 1956. Since, at least, 1990 no Republican candidate for governor has won the county.

It is located in New Mexico's 3rd congressional district, which has a Cook Partisan Voting Index rating of D+7 and is represented by Democrat Ben R. Luján. In the New Mexico legislature it is entirely represented by Democratic politicians.
