Background
Marty Walsh was elected to the mayoralty of Boston, Massachusetts, in the 2013 and 2017 elections. On January 7, 2021, President-elect Joe Biden announced that he would select Walsh to serve as the United States Secretary of Labor. Walsh resigned as mayor on March 22, after being confirmed as Secretary of Labor, and was replaced as acting-mayor by Kim Janey, who also served as president of the Boston City Council.The city council voted to move the primary election date from September 21 to September 14, in order to allow mail-in voting ballots for the general election an additional week of distribution time, which was approved by Mayor Janey.
