Buena Vista County has mostly voted Republican throughout its history, only failing to back the party's candidates in a presidential election eight times throughout its history. The first of these instances was in 1912 when the Republican vote was split between incumbent William Howard Taft & former President Theodore Roosevelt, who won a majority of the county's votes as a third-party candidate. Five of the instances were national landslides for the Democratic Party in all four of Franklin D. Roosevelt's victories as well as Lyndon B. Johnson's 1964 landslide. The other two Democratic victories were in 1948 as Harry S. Truman narrowly won the county & statewide by a similar margin, & 40 years later in 1988 as Michael Dukakis was boosted statewide by the 1980s farm crisis despite his national landslide loss.
