No, felons can't vote...........At least not in any State that I know of.
No I'm talking about after they are released. In Florida, and many States, particularly Red states, they make it very difficult for convicted felons to have their civil rights restored. Once again, it's because a large percentage of felons are blacks and the Republican governors in the South don't want them to be able to vote. Our previous governor Charlie Crist made it easy for released felons to have their civil rights restored and then our latest governor (Scott) rescinded the law to make it almost impossible. In Florida you used to be able to get back your right to vote in a year or two, but good luck with ever getting your right to go hunting again.
But, at the same time, most of the Southerners love the 2nd amendment even more and they hate stripping any one of the right to bear arms. Kind of a catch 22. I think it was in Louisiana that they overturned a law about felons and guns and decided that even if they were convicted felons, they still had the right to carry firearms. I find it all very bizarre.
