On Andrea Mitchell Reports today, Mitchell wondered aloud if, after a mass resignation of top aides yesterday, Newt Gingrich’s calamitous run for president was about to cue a fat lady with a song. New York’s John Heilemann agreed, comparing Gingrich to Wile E. Coyote running around with his head chopped off, due to his decision to appear at Monday’s Republican debate. Well, if the departing staffers wasn’t enough to end Gingrich’s run, we all knowwhat Mitt Romney Rick Perry does to wily coyotes.
