Historically, Jefferson County has heavily favored presidential candidates from the Republican Party. It is noted for being one of the few counties in Iowa that never voted for Franklin D. Roosevelt in any of his four presidential campaigns, along with having never given a Democrat who carried the county over 60% of the vote. In recent decades, politics within the county have become more competitive. Since 1992, the county has been carried by the Democratic presidential candidate in every election with the exception of 2000, when George W. Bush carried it with a plurality. The last Republican to win the county with a majority of the vote was Ronald Reagan in 1984. In the 1996 presidential election, Jefferson County was the only county in the entire country to give any (winning) candidate less than 40% of the vote, with Bill Clinton winning the county 35.1% to Bob Dole's 34.4%. In 2016, Donald Trump received a plurality of the votes in Jefferson County.
