SPRINGFIELD, Ill. — Democratic presidential candidate Barack Obama is calling his running mate, Joe Biden, "a leader who is ready to step in and be president."

Obama and Biden appeared together Saturday at a huge rally in Springfield, Illinois, their first joint appearance since Obama tapped Biden to be the Democrats' vice presidential candidate.

Freshly printed signs saying "Obama/Biden" sprouted in front of the Old State Capitol as thousands gathered for the rally.
