A very interesting research project for New Hampshire FReepers would be to get a copy of the check in records for your town. (They are probably a public record, like voter registrations)
See who voted absentee - since that is marked on the checklist.
Carefully, without annoying or bothering anyone, check to see if the individuals who voted absentee really are NH residents, or people who moved out of state but still voted here.
Share your results.
