Perhaps this is something of an existential question. But do we really have to pretend that Rudy Giuliani has more than a snowball's chance in hell of getting the Republican presidential nomination? Or can we all just stipulate that a multiple adulterer, who supports gay civil rights and choice, has deep and on-going ties to mobbed-up and now-disgraced Police boss Bernie Kerik, has a largely unscrutinized (outside of New York) resume, and had the bright idea of locating the NYC disaster center in the already-once-bombed World Trade Center probably will have some rough sledding in Republican primaries?
