PHILADELPHIA -- Sen. Hillary Rodham Clinton says she has something in common with legendary film boxer Rocky Balboa -- she's not a quitter. Recalling a famous scene on the steps of the Philadelphia Museum of Art from the 1976 Oscar-winning film "Rocky," Clinton said that ending her presidential campaign now would be as if "Rocky Balboa had gotten halfway up those art museum steps and said, 'Well, I guess that's about far enough.'"
