El Paso County sits at the Texas-New Mexico-Chihuahua junction and delivers some of the state's most consistent Democratic margins, driven by a population that is roughly 82% Hispanic — making it a key data point for tracking Latino electoral trends.
The Democratic margin in El Paso County peaked at seventy-three points in 1936. By 1988 the county had flipped, voting Republican for the first time in many years. The 2024 margin was fifteen points, the most Democratic-leaning result in the county's modern history.
The economic context is the key. El Paso County's median household income of $59,806 sits well below state and national norms, and 19% 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 Santa Cruz County and Los Angeles County.
