Joe Lieberman says you're retreating from the agenda that Democrats have made advances on since 1992. Bill Clinton was an extraordinary, exceptionally gifted president. I don't think anybody in this race has anything close to the talent Bill Clinton had. I don't think anybody in our generation will have that talent. The last person who had it in the White House was Franklin Roosevelt, in my view. But times are different. The country has moved further and further to the right. What we really need is somebody who is going to move it back to the center. That's what I'm going to try to do.
