Colin Dalai Lama Powell
I always thought these two seventy year olds looked alike (Dalai Lama is 73 and Powell is 71). In fact I've often mixed them up when scanning images.
As Scott states, I too hope that Powell's thoughtful, convincing endorsement of Obama has a positive affect on "the undecided" voter or some centrist republicans.
Unfortunately for me, he still has no credibility. Like the Dalai Lama though.
