I think Sarah is above that.
I could understand endorsing him if, God forbid, he's the eventual GOP nominee, but there's no justification for backing his primary bid.

Of course this isn’t a real endorsement, but it is the next closest thing and being said during the primary. But, no, Palin is not going out on a limb against her base this early or as you said, in a primary fight. She doesn’t go out on limbs, at least when not not physically surrounded by her base chanting her name.
