Joe Biden says goofy things from time to time. He should have said 50 years instead of 500.

That said, he seems like a good person and well respected by those who know him. There is no way to really know these things, but I suspect that his years in the Senate and his knowledge of foreign affairs have been a big help to the President. If any of you who are throwing darts at him call yourselves Republicans, then I suggest you recall the saying about people who live in glass houses. Neither of your two most recent VPs is qualified to shine Biden's shoes.
