Massachusetts House of Representatives' 31st Middlesex district

Massachusetts House of Representatives' 31st Middlesex district in the United States is one of 160 legislative districts included in the lower house of the Massachusetts General Court.

[1][2] Since 2015, Michael Seamus Day of the Democratic Party has represented the district.

Charlie Baker (R) signed the state's new legislative maps into law on November 4, 2021.

With local precincts divided multiple ways, it will inevitably lead to chaos at the polls and make it impossible for voters to understand who their elected representatives are.
