According to The Sentencing Proect, an estimated 4.6 million Americans are currently unable to vote as a result of laws that disenfranchise persons with a felony conviction. These laws vary widely by state, but encompass general categories of felons in prison or jail, on probation or parole, and in 12 states, persons who have completed their sentence but are still subject to disenfranchisement.
Military veterans who have subsequently been convicted of a felony constitute a significant portion of the disenfranchised population. This briefing paper analyzes the available data and finds that an estimated 585,355 veterans are unable to vote as a result of a felony conviction. Approximately one of every eight disenfranchised persons is a veteran.
