Reasoning that life in the U.S.–Mexico border region is sufficiently different from life in non-border regions this paper asks whether proximity to the border has a significant impact on presidential voting. County level data from four border states, California, Arizona, New Mexico, and Texas, over five presidential elections, 1992–2008, are examined using a both cross-sectional and panel data analysis. The authors conclude that there is a border effect that favors Democratic candidates and that fades as distance from the border increases.
