You may vote absentee due to absence from town during normal polling hours, physical disability or religious belief. You can download an application from the Sec. of State website http://www.sec.state.ma.us/ele/elepdf/absentee/English-Absentee-Ballot-Application.pdf
This is the same application to use if you need to request absentee ballots for all 2018 elections.
Applications are at the Town Clerk's office, available on request, or can be made by written request stating residence, where to mail the ballot and your signature. You can also stop in during Town Clerk hours to fill out the application and vote in person.
