The words "favorite" and "politician" are not two words I would put together very often, frankly.
But, yes I have heard Newt Gingrich on Fox in the past and in those instances I tended to agree with him. He seems to have moderate conservative views on several things, which is the way I tend to lean. Too bad he messed up his political career or he'd do well with the way things are going these days. (sigh)
Yes Newt is a favorite in our household. We have 1 one his books. He has too much in the "closet" though to go any higher and he is honest enough to know that. He does his best work right where he is. Another favorite is Leiberman. None are without fault, then neither are we.
