In Rhode Island, when someone gets out of prison and voting rights are restored, if they were registered to vote before, they are re-registered at their old address. Arcane, but so important in helping people return to full civic participation.
I don't think so: http://www.elections.ri.gov/voting/votepolls.php … No-excuse mail ballots are an option - apply by April 7 for the Presidential Preference Primary https://vote.sos.ri.gov/Voter/VotebyMail …
