I don't think Hilary is winning Arkansas. Once they find out about how she is an actual liberal and not just the wife of a former president/governor. I wouldn't take this too hard, in the end, I expect republicans to win the state by a Bush 2004 margin. If another democrat gets elected, I expect the margin to be a little larger. You can argue against me, but I don't think this small lead will last.
It's not so much that people think she'll win, just that she's digging into the GOP coalition. The GOP desperately needs to GAIN support right now, they can't afford to lose any of the support they currently have,
