Joe Biden is tough, brilliant, honest, and has tremendous credentials, especially in the field of foreign policy. He is highly respected by leaders around the world. His reputation among his fellow legislators is that of an honest broker and a hard worker.
But, without question, he is subject to verbal gaffe. I think it results from confidence, openness, candor, and honesty. That is his only baggage, if you wish to describe it as such. He is highly worth it.
