The fact is, it makes no sense for this to be coming from liberals. They'd be far better letting this ride until Cain had won the nomination, or just letting the GOP eat its own. This is out because the GOP doesn't want some 'upstart' taking control of their election. And that has Rove's face all over it. He's their point man against the Tea Party. And his associations with Romney, Perry (I don't for a minute believe that some little spat is more important than the GOP maintaining control over this election), and people within the NRA are a sure place to look for who's behind this.
Rove is two-faced. One face is Mitt, and the other is Rick.
