The 2024 Massachusetts Democratic presidential primary took place on March 5, 2024, as part of the Democratic Party primaries for the 2024 presidential election. 92 delegates to the Democratic National Convention were allocated to presidential candidates, with 24 additional unpledged delegates. The contest was held on Super Tuesday alongside primaries in 14 other states and territories and its Republican counterpart.
Incumbent Joe Biden won the primary with just over 80% of votes, as a campaign for "no preference" delegates, inspired by similar success in Michigan and on the same day in Minnesota, received 1 district delegate as the result of a protest vote against American support during the Gaza war, and placed ahead of candidates Dean Phillips and Marianne Williamson by collecting 9% of votes. It was one of three primaries on Super Tuesday, in which not all delegates went to Biden.
Incumbent President Joe Biden announced on April 25, 2023, his bid for a second term. He faced primary challenges from author, progressive activist, and 2020 presidential candidate Marianne Williamson and U.S. Representative from MN 3, Dean Phillips. The following candidates were placed on the ballot by the Secretary of the Commonwealth:
In addition, Massachusetts also places a no preference option on presidential primary ballots, and liberal activist Cenk Uygur was recognised as a write-in candidate.
There are three ways for a presidential candidate to get on the primary ballot in Massachusetts: a candidate can be placed on the ballot by the state party, they can gather 2,500 signatures to achieve ballot access, or the Secretary of the Commonwealth can place candidates who have been "generally advocated or recognized in the national news media." The Massachusetts Democratic Party voted to submit only Biden's name to the state ballot, which was highly criticized by the Williamson campaign, which did not attempt to file any signatures. Ultimately, both Phillips and Williamson were placed on the ballot by Secretary of the Commonwealth William Galvin.
