The 2024 Illinois Democratic presidential primary took place on March 19, 2024, as part of the Democratic Party primaries for the 2024 presidential election, alongside three other states. 147 delegates to the Democratic National Convention were allocated in an open primary, with 30 additional unpledged delegates. The contest was held alongside the primaries of Arizona, Kansas, and Ohio.
President Joe Biden again won all delegates with little opposition, receiving more than 80% of the vote in every county. Marianne Williamson and Dean Phillips placed second and third the second time on this day (the ninth time it happened overall).
Unlike many states, individual district delegates were elected directly by voters, with the slate of statewide delegates selected by the district delegates afterwards.
Candidates The petition circulation period for a candidate to place their name on the ballot began October 7, 2023, and ended January 5, 2024. Each candidate needed no less than 3,000 and no more than 5,000 signatures statewide. During the January 4, 2024, to January 5, 2024, filing period, four candidates filed to run in the Democratic primary.
