Agreed. Felons should be allowed to vote. Pirsoners should be allowed to vote. Just because you committed a crime doesn’t mean you shouldn’t be allowed to participate in a democratic election. There is, as far as I can remember, nothing in the Constitution that bars felons or the incarcerated from voting.
Not to mention that people in jail waiting for trial who can’t afford bail aren’t allowed to vote either if the election happens while they’re in jail, even though there’s been no conviction.
