Joseph Robin Biden III aka Beau didn’t want his dads name. Hmmmm. Really, wHY? “When I went into Iraq — I was there for five times — when he was in Baghdad. (Laughs.) And I remember, the first time I saw him, his name was “Hunter.” I said, “What in the hell happened?” He said, “Dad, I didn’t want anybody to do me any special favors because my Vice President is my dad.” He got permission to put a different nametag on.”
