Candidates

Ballot access controversy
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.
