Palin is hated by the rinos, no question of that.
Probably 15 years ago a local radio host said the political debates of our time are not right versus left but inside versus outside, and so it has been ever since, even inside the 'Pub party. 'Establishment' is not just a matter of circumstance but of world view.
I wish there was a little less 'establishment' in the mindset of some fellow posters. It appears in the form of clucking disapproval at the latest appearance of Palin.
