You won't see Sarah stumping for Brown... He's a pro Abortion RINO.
Palin is a REAGAN fiscal and social conservative and if the candidate is a little "off the farm" she could care less.
Don’t know a whole lot about Brown but I heard he was a bit squishy on abortion but not really solid pro. (I.e. anti late term, for consent, etc.) If that is the case then good for Sarah.
