You touch on an important aspect of voting where it does become a “right” albeit the situation where you lose that right. I found that in 46 states and D.C., criminal disenfranchisement laws deny the vote to all convicted adults in prison; 32 states also disenfranchise felons on parole; 29 disenfranchise those on probation. And, due to laws that may be unique in the world, in 14 states even ex-offenders who have fully served their sentences remain barred for life from voting.
Many states are now exploring “Restorative Rights” reforms as part of their justice reform measures. My organization, Collins Center for Public Policy has an initiative, http://www.SmartJusticeFlorida.org , that is looking into both social and economic justice reform measures. Thank you for your thoughtful comments.
