define not leading a productive life.
If they cannot hold a job, pay taxes, pay child support if they have children, or are defendants/respondents in civil disputes, they are not productive members of society. There are probably more if more thought was given to it.
if he hasnt reformed he has not met the terms of his parole or probation so no vote for him and he is likely to end up incarcerated again so no vote.
"Reform" is not a condition of any probation or parole order I have ever seen. "Reform" is a liberal philosophical belief not based in fact IMO. If you asked an incarcerated person what they want, I believe reform is waaay down the list of answers you would get (unless you are a member of a parole board). Getting out is at the top of the list. Anyone who is incarcerated is willing to do, act, or say ANYTHING to get out. The true test of reform is actions after release and completion of parole and probation. Additionally I would like to know if there is a federal parole program or if it is still as it used to be that a federal prisoner released has fully completed the sentence.
Maybe there should be a "felon voter" program requiring the warden to make voter registration documents available to every prisoner being released. This would complement the "motor voter" legislation.
