Those are not things that are characteristic of someone who should be running the country. The ramifications are extensive. Nothing about being President or considering it should be taken lightly. There are appropriate and inappropriate behaviors...THAT was NOT appropriate for anyone seeking the status of President. Having a sense of humor has nothing to do with the issue at hand. Nice attempt at deflecting responsibility for Rudy, though it misses the real mark.
I don't think that he was thinking of the presidency at the time, and in any event, dressing up and acting in a dumb skit hardly outweighs rescuing NYC from the trash heap.
