Whose Rush standing behind these days?
He is yet to say and most likely won't until the field is set and right before the primaries, but when speaking of Sarah, it is in an obviously different light when compared to any establishment politico.
But then again, he is proned to not endorse anyone but instead comment on the debate by agreeing or disagreeing with policy statements made by each candidate. It is in that commentary where we will know where he sides, without naming anyone. Essentially, he would be foolish to go out on a limb but instead wise to use his pulpit to help shape the debate.
