Perry and Palin are good friends, apparently, so if she was going to endorse anyone, it would probably be Rick. After all, she has done it before!
It could easily happen, though Palin is very low-key these days...she might save her endorsement for a time of Maximum impact...
I should add that I’m not gloating. I’m just ready to mow down zero with the candidate who now has a clean, uncluttered shot at him. What with the background noise eliminated.
