In the UK people in jail (so a subset of convicted people) are not allowed to vote. The argument is that while you are detained in jail you are being punished by loss of civil rights and that voting is one of these.

As far as I understand, in Florida even people with past felony convictions can't vote, even if they served their sentence.
