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. Illinois voted to the right of Colorado for the first time since 1964.

The 2024 Illinois Green Party presidential primary was held from March 2 to March 16, 2024, in the U.S. state of Illinois as one of the Green Party's state primaries ahead of the 2024 presidential election. It was run by the Green Party of Illinois. It was an online vote, limited to dues-paying state party members.

General election Candidates

On August 23, 2024, the Illinois State Board of Elections met in Chicago and Springfield to certify the following list of candidates to appear on the general election ballot: Kamala Harris / Tim Walz — Democratic Donald Trump / JD Vance — Republican Robert F. Kennedy Jr. / Nicole Shanahan — Independent The board also issued rulings to the nomination papers of third party and independent candidates, including placeholder candidates for the Libertarian and Green Party tickets, as well as for Kennedy and Shanahan. Both the Libertarian and Green tickets were removed from the ballot, lacking the minimum required number of 25,000 valid signatures, while Kennedy remained.

Campaign Convention

The 2024 Democratic National Convention was held from August 19 to 22, 2024, at the United Center in Chicago. It was the first instance of a major party's presidential nominating convention held in Illinois since 1996. Here, party delegates voted on their platform for the election and formally nominated vice president Kamala Harris as the Democratic nominee, with Minnesota governor Tim Walz as her running mate.
