When you’ve committed a felony! Just two states allow convicted felons to vote without restrictions. Twelve states empower themselves to permanently bar convicted felons–including those who have served their sentences and completed probation and/or parole–from voting. This chart from ProCon.org is worth a look.
It may not be terribly surprising that people who violate the laws of a state might have their membership, as it were, temporarily or permanently suspended, the equivalent of banishment within borders. But the interesting thing is that these felons do not disappear in any other sense. They are counted as residents of the county in which they are incarcerated, for example, population counts which have real effects on the appropriation of resources and political influence. So it’s a double-whammy for the African-American felons locked up in rural areas in states like Mississippi and Virginia… not only do they lose the right to vote, but their presence in prisons actually empowers politicians who may not have their interests at heart, and have an incentive to keep their prison full.
This is relatively idle speculation, but it is somewhat backed up by Marie Gottschalk, who wrote the excellent The Prison and the Gallows. In 2007, Gottschalk wrote,
In Pennsylvania and 47 other states, imprisoned felons are barred from voting. Yet these disenfranchised prisoners are included in the population tallies used to draw legislative and congressional districts.
This practice dilutes the votes of urban areas such as Philadelphia and Pittsburgh. Nearly 40 percent of the 45,0000 inmates in Pennsylvania’s state prisons come from Philadelphia. For census and redistricting purposes, these urban citizens “reside” in counties far from their homes, often in rural districts that are Republican strongholds.
It’s diabolical. One solution to this particular issue is to change how the census is taken. It’s not clear whether that will happen, especially in this politically polarized, and thus stagnant, climate. And the other solution–incarcerating fewer people, especially for non-violent offenses–is certainly a no-go in this tough-on-criminal country.
