The 2020 United States presidential election in Illinois was held on Tuesday, November 3, 2020, as part of the 2020 United States presidential election in which all 50 states plus the District of Columbia participated. Illinois voters chose electors to represent them in the Electoral College via a popular vote, pitting the Republican Party's nominee, incumbent President Donald Trump of Florida, and his running mate, Vice President Mike Pence of Indiana, against Democratic Party nominee, former Vice President Joe Biden of Delaware, and his running mate, Senator Kamala Harris of California. Illinois had 20 votes in the Electoral College. Prior to the 2020 election, all news organizations predicted Illinois was a state that Biden would win, or otherwise considered a safe blue state.
Biden carried Illinois, winning 57.54% of the vote to Trump's 40.55%. Libertarian nominee Jo Jorgensen, a native of Grayslake, won 1.1% of the state's vote, with other minor candidates winning less than 1%. Illinois was one of five states in the nation in which Biden's victory margin was larger than one million raw votes, the others being California, Maryland, Massachusetts and New York.
Per exit polls by the Associated Press, Biden's strength came from a coalition of key Democratic constituencies: he garnered 92% of votes from Blacks; 70% from Latinos, including 69% of Latinos of Mexican heritage; 53% from union households; and 50% of Whites.
Primary elections Illinois held its primary elections as scheduled, despite concerns over the COVID-19 pandemic in the United States. Election officials in Illinois acknowledged that they believed turnout was unusually low.
