Hard to believe, but Vice President Joe Biden's long political career was almost derailed by a speech disorder. "When I was with people I didn't know, I used to t-t-t-talk l-l-l-like that," Biden told NPR
in 2007. In his book "Promises to Keep," he wrote that even if he could, he wouldn't have changed anything. "That impediment ended up being a godsend for me," he said. "Carrying it strengthened me and, I hoped, made me a better person."
