The 2024 Maine Democratic presidential primary took place on March 5, 2024, as part of the Democratic Party primaries for the 2024 presidential election. 32 delegates to the Democratic National Convention were allocated to presidential candidates.[1] The contest was held on Super Tuesday alongside primaries in 14 other states and territories. This was a semi-closed primary where party members may only vote in their respective party's primary, but unenrolled voters may choose a party's primary to participate in. This change in law from Maine's previous closed primary went into effect on May 14, 2022, without Gov. Janet Mills' signature.[2]
Biden won in a landslide, with some opposition from Philips, who won almost 7% of the vote.
