Alamosa County is a competitive swing county, voting for the winning Presidential candidate in every election since its formation except 1944, 1960, 1976, 2016, and 2020. In the 2016 election, Donald Trump – who captured several previously solidly Democratic counties in southern Colorado – became the first Republican to win the presidency without carrying the county since it was created before the 1916 election. Trump flipped the county in 2020, the only one in Colorado, and one of only fifteen nationally, which he turned from blue to red that year.[a]
