The 2016 United States Senate election in Iowa was held November 8, 2016, to elect a member of the United States Senate to represent the State of Iowa, concurrently with the 2016 U.S. presidential election, as well as other elections to the United States Senate in other states and elections to the United States House of Representatives and various state and local elections.
Incumbent Republican Senator Chuck Grassley won reelection to a seventh term in office. Primary elections were held June 7, 2016, with Grassley facing no primary opposition, and former lieutenant governor Patty Judge winning the Democratic nomination. Grassley won a seventh term in a sixth consecutive landslide and outperformed Donald Trump, who also won the state that year; nevertheless, this represented Grassley's worst re-election performance at the time since his first race in 1980, until 6 years later when Michael Franken would not only make Grassley fall below 60% of the vote, but also cut his winning percentage in half and flip several counties (namely Black Hawk, Linn, Story and Polk) that Grassley carried in this election.
Republican Chuck Grassley was first elected to the Senate in 1980, defeating Democratic incumbent John Culver by 53% to 46%. Since then, Grassley has been re-elected five times, most recently in 2010, on each occasion taking at least 64% of the vote.
Despite speculation that Grassley, who turned 83 years old in 2016, might retire, he announced in September 2013 that he was "making plans to run for re-election", but added that "it's not taking much of my time. I'm concentrating on doing my job for Iowans."
