If Palin runs; no deals on running with a RINO.
If she runs, I'd peg her likely running mate as either Josh Bolton or someone she knows, has endorsed, and is friends with or feels comfortable with, and who has experience.
Not to many folks fit that bill (she is not a beltway type, she was from Alaska, and is anti-establishment). My guess is her running mate would probably be Bolton because of his foreign policy background, but I could easily see her picking Perry (well, now I can, not before).
