"The more complicated truth, say top GOP officials from both wings of the party, is that an ornery conservative base is expressing its disgust for Republicans who have both flagrantly defied the party and represent a distrusted political establishment."
What is sad is that the GOP is a party of "if you are different, get the hell out." So many moderate republicans are on the verge of extinction. And the trouble for the GOP is that with the "anti-incumbent" atmosphere right now, the gains they get in november will only embolden the radicals. So come 2012, they are going to nominate, in their primaries, radicals that are unelectable.
