I freakin’ love David Letterman sometimes and this is one of those times. The good stuff starts at about the 3:45 mark and he brings up a very interesting point. If a candidate running for president gets called away for a national crisis- you don’t suspend your campaign, you put it in the capable hands of your number 2. By not doing so, John McCain has just publicly admitted that Sarah Palin is in water way over her perfectly coiffed head. She simply can’t do the job and even he knows it.
