The 2008 United States presidential election in Illinois took place on November 4, 2008, and was part of the 2008 United States presidential election. Voters chose 21 representatives, or electors to the Electoral College, who voted for president and vice president.
Democratic nominee Barack Obama won his home state by a 25.1 percentage point margin over Republican nominee John McCain. Prior to the election, every major news organization considered Illinois a state Obama would win, or otherwise a safe blue state. One of the most reliably blue states in the nation, Illinois has not voted for a Republican presidential nominee since 1988, when George H. W. Bush narrowly carried the state. In 2008, continuing that trend, it appeared that a generic Democratic presidential nominee could have easily won Illinois; it was no surprise then that Obama, who represented Illinois in the U.S. Senate, won the state in a landslide victory, clinching near 62 percent of the total vote.
As of the 2020 presidential election[update], this is the last time a Democrat won the following counties: Boone, Bureau, Cass, Calhoun, Coles, Gallatin, Grundy, Kankakee, LaSalle, Macon, Macoupin, Madison, Mason, McDonough, McHenry, Montgomery, Pulaski, Sangamon, Schuyler, Stephenson, and Vermillion.
As of 2020, Obama is the only presidential candidate of either party to win the state with more than 60% of the vote since Warren G. Harding in 1920, and the only Democrat to do so since Andrew Jackson, the Democratic Party's first presidential nominee, in 1828 and 1832. McCain's 36.78% of the vote is the second-lowest of any major-party nominee since 1924, only surpassing George H. W. Bush in 1992, when a substantial amount of the vote went to Ross Perot’s candidacy as an independent.
Illinois was one of three states where Obama outperformed Franklin D. Roosevelt in all four of his runs, as well as Lyndon Johnson in his 1964 landslide. The others were rapidly Democratic-trending Vermont and Delaware, the latter being the home state of Joe Biden, Obama's running mate.
