Republicans only will win Montana, South Dakota and West Virginia, while losing Kansas to an Independent, for a net gain for two. Arkansas might fall, but it's far from a guarantee. Everything else will go Democratic.
Isn't it more likely that Louisiana will fall than Arkansas, since she will actually need 50% of the vote in order to survive? And as far as I can remember, she hasn't been even near that number in any polls so far. I hope I'm wrong though.
If I could chose, I'd rather want Louisiana to go Democratic than Arkansas.
