wanted to be president of the united states since '88. he said recently he may not have the emotional fuel, was how he phrased it. if he doesn't run, then he knows he would really ultimately be saying good-bye to a dream of the oval office. if he runs and loses, the question is can he take that kind of loss, especially after mourning the loss of beau. which do you think would be more challenging for the heart to take? >> well, look, it was the only cure for presidential ambition is embalming fluid. so there's a lot going on in joe biden that says if there's even a small sliver of a chance, he has to go for it. so i think he would probably if we're going to put him on the couch and analyze that, probably he would take a loss much more easily than the what ifs of wondering what might have been.
