Can you vote with a felony in New Hampshire?

After prison.

In New Hampshire, people lose the right to vote only while in prison for a felony. It comes back on release, including on parole or probation. Some other convictions can affect it too; the details are below.

The exception: People convicted of treason, bribery or a willful violation of New Hampshire or federal election laws lose the right to vote unless the New Hampshire Supreme Court restores it.
