Politics

[edit]

Historically, Jefferson County heavily favored presidential candidates from the Republican Party. It is noted for being one of the few counties in Iowa that never voted for Woodrow Wilson, along with having never given a Democrat who carried the county over sixty percent of the vote. In recent decades, politics within the county have become more competitive. From 1992 to 2012, the county had been carried by the Democratic presidential candidate in every election with the exception of 2000, when George W. Bush obtained a plurality. In the 1996 presidential election, Jefferson County was the only county in the United States to give any (winning) candidate less than forty percent of the vote, with Bill Clinton winning the county 35.1% to Bob Dole's 34.4%. In 2024, Donald Trump became the first Republican to win a majority of the votes in Jefferson County since Ronald Reagan's 1984 performance. The county has been the strongest basis of support for the Natural Law Party's presidential campaigns, due to the presence of the Maharishi Vedic City and Maharishi International University.
