At 61, the host of CBS' "Late Show" has officially entered his late-career cranky-pants phase, and proven anew his national relevance. When McCain blew off a scheduled appearance in late September, Letterman went ballistic on-camera, impugning the candidate's much-storied heroism and ridiculing Palin.
When McCain finally rescheduled to offer a mea culpa, he probably wished he hadn't bothered: During the tense chat, Letterman's unexpected dig at McCain's friendship with Watergate felon G. Gordon Liddy caught the Arizona senator visibly off-guard.
However: The McCain flap really didn't do much for "Late Show's" ratings.
