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
Applications can be picked up outside the Town Clerk's office, or mailed upon request, or sign a simple note, stating your residential address, where to mail the ballot and, if this is for a primary election and you are not enrolled in a specific party, please state which party ballot you want to receive. You can also fill out the application and vote absentee in person during Town Clerk hours.
