Politics

Owing to its border location and Hispanic majority population, Santa Cruz is a strongly Democratic county. The last Republican to win the county was George H.W. Bush in 1988, and although the Republicans won the county in six consecutive election from 1968 to 1988, three of these wins were by very narrow margins. Increasing Mexican immigration and fear of Republican opposition thereto has turned it even more solidly blue: in 2016 Hillary Clinton won over 70 percent of the county's vote, approaching figures typical of long-time Democratic strongholds in South Texas. In the process it took over from Apache County as the most Democratic of the state's counties.
