There is something deeply personal about Beck's distaste for Gingrich and I think he is being (uncharacteristically) dishonest in avoiding the source of his dislike for the man. Mitt Romney is clearly and by any reasonable measure far more of a liberal Progressive than Newt, and yet, Beck continues to claim otherwise for reasons about which he is not coming clean with his audience - and which they deserve to hear.
Follow the money.
Although I think the Mormon connection (which is likely a money connection as well) is part of it; and Beck may have fallen off the wagon.
Whatever the reason or justification, his actions now will undermine his past performances, where he educated the public about Alinsky, Cloward-Piven, etc.
