>most who go to prison can never vote again.
Not to be pedantic, but only 13 states, mostly in the south, disenfranchise people with felony convictions for life. Everywhere else, anyone who has completed their sentence -- and in many cases, people on probation and/or parole -- are allowed to vote.
A big problem is that many ex-offenders *believe* that they have permanently lost thier right to vote, and very little effort is made to inform them otherwise.
