Mesa County, centered on Grand Junction, has voted Republican in every presidential race for decades, with its energy-sector economy and rural geography reinforcing margins that routinely exceed 20 points.
The Democratic margin in Mesa County peaked at sixty-four points in 1896. By 1968 the county had flipped, voting Republican for the first time in many years. The 2024 margin was twenty-four points, the most Republican-leaning result in the county's modern history.
The economic context is the key. Mesa County's median household income of $73,658 sits well below state and national norms, and 11% of residents live below the federal poverty line. The shift here is part of a broader realignment of working-class places across the country. The county's voting pattern over the last decade is most similar to that of Montrose County and Delta County.
