2024 United States presidential election in Illinois

The 2024 United States presidential election in Illinois took place on Tuesday, November 5, 2024, as part of the 2024 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. The state of Illinois has 19 electoral votes in the Electoral College this election, following reapportionment due to the 2020 United States census in which the state lost a seat.

Illinois is a strongly blue state in the Great Lakes region anchored by Chicago, with the sparsely populated southern region of the state being culturally influenced by the Upper South and Bible Belt. It has a reputation for being by far the most liberal state in the Great Lakes region. The state has voted for the Democratic candidate in every presidential election beginning in 1992 (doing so by at least 10% each time), including voting for Senator Barack Obama from Illinois in 2008 and 2012 and Chicago-born Hillary Clinton in 2016. This was the first election since 1868 in which Illinois did not have 20 or more electoral votes.

Illinois was won by the Democratic candidate Kamala Harris. Illinois shifted noticeably towards Trump, with Harris winning the state by under an 11 point margin, six points down from Biden. The state’s red shift was caused by low Democratic turnout in Cook County, home to Chicago with Harris receiving about 300,000 fewer votes than Biden in Cook County, while Trump ran marginally ahead of his 2020 raw vote total in Chicago, Cook as a whole, and statewide. Trump became the first Republican to win the White House without Kendall County or McLean County.
