Boston
Boston is preparing for the Preliminary Municipal Election on September 9, which will narrow the field of mayoral candidates to two finalists and determine the leading choices for District City Councilor and At-Large City Councilors. Key voter deadlines and early voting opportunities are set to ensure ballots are cast and counted in a timely, accessible manner.
What voters need to know now
The registration deadline for new voters is August 30. New registrations can be completed in-person at municipal offices until 5:00 p.m., online until 11:59 p.m. on August 30, or by mailing a registration application that is postmarked the same day. Early voting opens on August 30 and runs through September 5, with a pause on Labor Day, September 1. City Hall will serve as the main hub for early voting and will offer extended hours to accommodate more voters. Detailed early voting times and locations are available from the Election Department.
Voting by mail and accessible voting
Applications for mail-in ballots are due by September 2. Ballots may be requested online through the Secretary of the Commonwealth’s ballot request system or by visiting the City’s Election Department in person. Accessible options include an Accessible Electronic Voting System for voters with disabilities. There is a Tuesday deadline for applying for accessible ballots; voters seeking these accommodations should consult the Election Department for specific procedures and exact deadlines.
Polling places, technology, and accessibility
On Election Day, polls will be open from 7:00 a.m. to 8:00 p.m. The city will operate 275 precincts using electronic Poll Pads to facilitate check-in and registration verification. Polling locations will offer AutoMark Voter Assist Terminals and language interpretation options to improve accessibility for voters with disabilities and voters who prefer languages other than English. Early ballots will begin processing prior to election night and will enter the central tabulation system so that counting can proceed promptly after polls close.
Media, exit polling, and results
Media presence at polling places will be regulated to protect voter privacy and maintain orderly access. Press crews must maintain distance from voting activity and are prohibited from photographing marked ballots. Exit polling is allowed but must be conducted at least 150 feet away from building entrances to avoid obstructing voter access. Unofficial election results, including early and mail-in votes, will begin to be released after polls close at 8:00 p.m. on September 9.
Candidates and next steps
The preliminary ballot for mayor includes incumbent Michelle Wu and challengers Josh Kraft, Robert Cappucci, and Domingos Darosa. The top two vote-getters in the preliminary will advance to the general election, which is scheduled for November 4. Voter registration for the general election remains open until October 25, and early voting for the general election will run from October 25 to October 31.
How the process supports timely counting and accessibility
Early ballot processing and entry into central tabulation are designed to speed result reporting on election night. The combination of in-person early voting, expanded City Hall hours, mail-in ballot options, accessible electronic systems, and technology at polling places aims to provide multiple ways for voters to participate while maintaining security and privacy during voting and counting.
