A good description of Ann is: acid tongued, rapier witted, and brass overies. But she fills a necessary role. Consider the following (as Bill Nye Science Guy would say): the American Socialists say "at least we aren't Communists", and the American Liberals say "at least we aren't Socialists" (though they really are). So from the liberal perspective, a garden variety conservative is a right winger. Ann Coulter provides some badly needed perspective. Her rhetoric is useful because the further out she goes, the more moderate conservatives look even to liberals. Plus she focuses the attention of the liberals so they are all baying after her while the regular conservatives focus on getting work done.
Plus, while she swings for the fences and so misses some of the time, overall she is correct. The Leftists are traitors, in that they are "adhering to their [the United States] Enemies, giving them Aid and Comfort."
No offense, but I have had my fill of Ann. She is starting to sound to me like Pat Buchanan.
She is smart enough to be the newest Peggy Noonan instead of the latest Phillis Schlafley.
