Barack Obama introduced Sen. Joe Biden of Delaware as his running mate Saturday, hailing him as a "leader who is ready to step in and be president."Before a crowd of thousands gathered in front of the Old State Capitol in Springfield, Ill., Obama said Biden was "what many others pretend to be ââ¬â a statesman with sound judgment who doesn't have to hide behind bluster to keep America strong."
