The high-priced hooker who sunk Gov. Spitzer's political career was a party pal of one of his top financial backers, boozing it up with him at clubs and his palatial Hamptons mansion. James Chanos, 50, a billionaire hedge fund manager who runs Kynikos Associates in Manhattan, says he met Ashley Alexandra Dupre - the girl at center of the gov love scandal - at a nightclub several years ago and often invited her to parties, But he denied introducing her to Spitzer.
