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. ___________
Accurate information isn't pedantry. I brought this subject up a couple of years ago and somebody looked it up: the results were (then) that in some states disenfranchisment was absolute and permanent; in some states there was no disenfranchisment; and in the rest there were varying waiting periods and a long path back to enfranchisement...applications to fill out, bureaucratic hurdles to be jumped etc. To my mind, given the demographics of ex-felons, the folks in the last category are not likely to ever vote again.
Perhaps a lot has changed since then. I don't know.
