Houston County voted for conservative Democrats for most of the twentieth century, and gradually switched to voting for conservative Republicans closer to the century's end and into the twenty-first. In the2018 gubernatorial election, while she did not carry Houston County,Stacey Abrams improved on Democratic margins in the county, improving five percent compared toHillary Clinton's2016 presidential run and by four percent compared toBarack Obama's2008 run. Houston was one of five counties not carried by Abrams which improved their Democratic margins.[20] In 2020,Joe Biden improved Democratic margins to their best sinceJimmy Carter carried it in 1980.
