A little more than a year ago, when Bill Clinton was on the skids in the New York primary-the ridicule relentless in the tabloids and on the streets-he took a chance and exposed himself to the fastest, flippest radio talk-show jock in town, Don Imus.
For a year or so past he's held the hot air chair on the front end of one of these sightseein 'chariots, cheerin' the out of town buyers and wheat belt tourists with the flippest line of skyscraper statistics handed out through any megaphone in town.
