The Pryor family have run Arkansas longer than I've been alive.
David Pryor who is the father of Mark Pryor and was the US Senator before passing it down to his son was no real friend to gun owners. He made a few insignificant pro gun votes back in the day, but was a big supporter of the assault weapons ban. He showed his ignorance when he said that you didn't need assault weapons to hunt with. Goes to show the pos had no idea what the Second Amendment stood for. Not to mention he and Bill are good buddies. That should speak volumes of his character or lack thereof.
Arkansas is a big duck hunting state as is Mississippi, so I'm guessing most will be in favor of it, but I still think the rotten apple never falls far from the tree. Mark will almost certainly follow in Daddy's footsteps.
