In February and March of 2018, Massachusetts Democrats will meet in towns and wards across the state to elect delegates to the 2018 Democratic State Convention. Sometimes a sleepy affair, in years with competitive statewide races (for Governor or another of the Commonwealth’s several Constitutional Offices), the Convention is a critical hurdle for candidates hoping to appear on the Democratic Party’s September primary ballot. In order to do so, a candidate must receive the support of at least 15% of the delegates attending that year’s convention, usually held in June. In 2014, Governor Deval Patrick’s last year in office, there were initially five Democrat candidates seeking to succeed him. They were: Joe Avellone, Don Berwick, Martha Coakley, Steve Grossman, and Juliette Kayyem. Only three of five made it past the convention.
