I sense Rove and his continual Butthurt at our harming some of his work in this somewhere.
Rove is known for backing Romney. That said, Rove is a GOP establishment man. Rove was an early protege for Perry after Perry became a Republican. They fell out later during Romney's run for governor, but...
My suspicion is that Rove will be in it for any establishment candidate over any 'interloper' (read Tea Party favorite) such as Palin, Bachmann, Cain, or anyone who hasn't shown fealty to the establishment. And Perry, regardless of how he's painted, will get preference if the need arises. That's my suspicion, but I've seen nothing to warrant thinking otherwise.
