Government and politics
In the majority of U.S. presidential elections, Zapata County supported Democratic Party candidates. However, on three occasions, it gave record-setting margins to Republican presidential nominees, when it delivered the highest percentage of the vote of any county in the nation to them. First in 1896, when it gave 96.3% of the vote to William McKinley, though he lost Texas as a whole (with 30.8% of the statewide popular vote), but won the national election (with 51.0% of the nationwide popular vote). The second time in 1908, when William Howard Taft won 99.1% of the vote in the county, despite losing the state to Democrat William Jennings Bryan (and receiving just 22.4% of the statewide vote), but winning the national election (with 51.6% of the nationwide popular vote). The third and final time was in 1912, when it again gave then-incumbent President Taft 80.9% with it being his best county in the nation, but against the state and nation's preference for the Democratic victor, Woodrow Wilson (in the popular vote, Taft only received 9.5% statewide and 23.2% nationwide).
It voted Republican for President (Warren G. Harding) in 1920, and then consistently voted Democratic until 2020, when Republican Donald Trump defeated Democrat Joe Biden 52%-47%, about the same as the statewide margin.[12] Zapata was the most Hispanic county to vote for Trump in 2020, as well as the county with the lowest non-Hispanic white population to do so.
