“Florida is one of a handful of states, mostly in the Deep South, that make it all but impossible for felons to regain their right to vote after they complete their sentence. Currently, an individual has to petition the governor for an individual restoration of rights, and few such cases are granted. The process is designed to be as byzantine and as insurmountable as possible. In practice, for the vast majority of felons, disenfranchisement is a lifelong condition.”
