Registered Voters
Massachusetts publishes voter-registration counts by town through the Secretary of the Commonwealth; the counts below are the state’s enrollment snapshot from February 1, 2025. As in most of the state, Otis’s largest bloc by far is voters who choose no party at all, and in Massachusetts an unenrolled voter may still take either party’s ballot at a primary, which makes that bloc the one every candidate has to win.
- Total registered: 1,323
- Unenrolled (no party): 900 (68.03%)
- Democrats: 243 (18.37%)
- Republicans: 176 (13.30%)
By the time of the annual town election on May 26, 2026, the Town Clerk counted 1,377 registered voters, and 278 of them cast ballots that day and filled eleven town offices for the year.
