The 2020 United States presidential election in Iowa was held on Tuesday, November 3, 2020, as part of the 2020 United States elections in which all 50 states plus the District of Columbia participated.[1] Iowa voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump, and running mate Vice President Mike Pence against Democratic Party nominee, former Vice President Joe Biden, and his running mate California Senator Kamala Harris. Iowa has six electoral votes in the Electoral College.[2]

Trump won the Hawkeye State 53% to 45%. Prior to this election most news organizations had considered Iowa as either leaning towards Trump or a tossup. Iowa's bellwether status diminished in this election. This was the first time since 2000 when Iowa did not back the candidate who won the presidential election, and also the first election since 1988 when a candidate from either party would win the state of Iowa while losing both the popular and electoral vote. Biden became the first Democratic nominee since 1976 to win the presidency without carrying Iowa, as well as the first since 1940 to win the presidency without carrying Dubuque County. Trump underperformed his 2016 margins in the Des Moines metro, Cedar Rapids metro, and western Iowa, the latter which borders Nebraska's 2nd congressional district, an electoral vote he won in 2016 but lost in 2020. However, he improved in northeast and south Iowa.

Per exit polls by the Associated Press, Trump's strength in Iowa came from White Americans with no college degree, who comprised 62% of the electorate and supported Trump by 58%–40%. Trump swept all religious groups, garnering 66% of white Protestants, 54% of white Catholics, and 76% of white born-again/Evangelical Christians. 53% of voters believed Trump was better able to handle international trade.[3] Trump continued to win the cultural message among white voters.[4]
