John Fund on felon's right to vote: "The Constitution grants states the authority to determine 'the Times, Places and Manner of holding Elections,' but Hillary Clinton and John Kerry are pushing a Count Every Vote Act that would, among other things, force states to allow voters to register at the polls and declaring Election Day a federal holiday. And then they want to force every state to let felons vote--even though the 14th Amendment specifically permits states to disfranchise citizens convicted of 'participation in rebellion, or other crime.'"
Republicans in Congress have their own partisan motivations for opposing any enfranchisement of felons. Leaving the matter to the states probably will mean more felons regaining the right to vote than Republicans would like but fewer than Democrats desire. And that's probably about the right solution."
