Bernie Sanders' suggestion that all states should allow incarcerated people to vote, instead of re-enfranchising them one-by-one after incarceration, is a constructive way of bypassing the voting rights debate and getting right down to the idea that one remains a citizen even after being convicted of a crime.
One thing this would accomplish is discouraging the selective creation of laws and harsh punishment for “crimes” without a victim with the sole purpose of disenfranchising a group of people believed to be primarily Democrat voters. Crack laws anyone or drug laws in general.
Of course he is right and good to see him speak out on that. He will make a fine deputy to Tulsi Gabbard as President.
