I’ve been wondering the very same thing. Let me know if you get any replies to this. My read on rudy’s character is that he lacks the honor; he would go off the reservation in a heartbeat and already has done so. For instance, he once ran on the liberal ticket, and he also endorsed the democrat Mario Cuomo over the republican Pataki. He is a man with very few core honorable principles.
I think that he is gambling on a sure win in the primary and is already trying to run to the left of Hillary.
