2021 MassDems Platform Convention

On September 25, 2021, over 5,000 delegates will gather virtually and in-person at the Tsongas Center at UMass Lowell to discuss and decide on a Party Platform.


Throughout the summer voters across the commonwealth will caucus at the local level to select the delegates who’ll represent their town or ward at the convention. During platform hearings and through written testimony, delegates and Democratic activists will help the Platform Committee develop a draft of the 2021 Massachusetts Democratic Party Platform.
