The 2008 Illinois Democratic presidential primary took place on Super Tuesday, February 5, 2008, with 153 delegates at stake. Each of Illinois's 19 congressional districts was proportionally allocated to candidates who had received 15% or more of the vote in that district, totaling 100. Another 53 delegates were also proportionally allocated to candidates who had received 15% or more of the vote statewide. The 153 delegates represented Illinois at the Democratic National Convention in Denver, Colorado. Thirty-two other unpledged delegates, known as superdelegates, also attended the convention and cast their votes as well.
