Last November, Florida voters by a large margin passed an amendment restoring voting rights to most state citizens with felony convictions and who had completed the terms of their sentence. This breakthrough move of re-enfranchisement would restore rights to, potentially, 1.4 million people, undoing a small portion of the laws passed by conservatives in their efforts to curtail the voting rights of the poor and of non-whites, two groups that are disproportionately targeted by law enforcement to begin with.
Republican lawmakers in the state are obviously quite irritated with voters for this move and, mirroring conservative reactions to other voter-passed initiatives in other states, have been devoting themselves to finding ways of scuttling, sabotaging, or at least watering-down the new laws their own voters put in place. The most aggressive of these efforts is a bit of "clarifying" legislation declaring that ex-felons may only have their voting rights restored after completing not just the resulting jail time or probation, but after paying back all restitution, fines and fees associated with their court cases.
The intent of this broad apparent re-definition of the voters' will is self-evident. Those that are unable to pay court fees associated with their convictions tend to be, obviously, the very poor. And those that do pay those costs very often have arranged to do so, with court approval, over the course of months or years.
The Republican move, then, seeks to surgically target the poor. If you're a wealthy felon, perhaps the sort who makes regular appearances at Mar-a-Lago or whose parents are available to write the necessary checks, you get your voting rights restored immediately. And if you're not, you will be kept off the voting rolls—perhaps permanently. It is a neat little trick to use the voters' intentions to restore voting rights to the upper classes while scrapping the bits that would do the same for the lower classes, because of course it is. For Republicans, the game plays out the same way on every issue, in every state.
It is not clear whether this newest Republican effort will be successful. They likely have the necessary votes, but the voter backlash could be severe and there is still some question as to whether lawmakers are brave or stupid enough to rile voters so thoroughly immediately after such a broad and sweeping voter-ordered re-enfranchisment effort. If state Republicans succeed, it will likely result in another voter initiative in 2020 aimed at undoing the Republican changes.
