Politics
Between 1864 and 1928, Wapello County backed the Republican candidate in every election except 1912, when former Republican Theodore Roosevelt ran as the Progressive candidate, fracturing the Republican party and allowing Democrat Woodrow Wilson to take the county with a plurality of the vote of less than 37%. From 1932 to 2012, the county voted Democratic in every election except two, the nationwide Republican landslides of Dwight D. Eisenhower in 1952 and Richard Nixon in 1972. Beginning in 2016, Wapello County has shifted back to the Republican column, as Donald Trump carried the county in both 2016 and 2020, winning by a margin of over 20% in 2016 and over 23% in 2020. Also in 2020, Trump became the first candidate from any party to obtain at least 60% of the county's vote since Michael Dukakis in 1988, and the first Republican to do so since Herbert Hoover in 1928.
