If Hillary does truly have a 51 percent favorable rating in Arkansas, and this is not merely a statistical outlier or error, that would seem to be evidence that she is electable nationwide.
Granted, the home state factor from her husband helps her rating there I'm sure, but it's still Arkansas that we're talking about, hardly a must win state for a Democrat.
Could partly be a Bush factor also. With Bush's approval in last months SUSA poll 34% in Arkansas it could make them long for the days of Clinton and like any Clinton as a result.
