WASHINGTON (AP)- Call it the Biden Buzz. Part of the noise comes from the reporters swarming around Sen. Joe Biden. Yet all the speculation about Biden as a leading candidate for vice-presidential running mate may be saying a lot about what Barack Obama's campaign lacks.
Biden is staying uncharacteristically quiet in the face of growing attention as Obama nears a decision on his running mate. Dressed in a suit and sunglasses, Biden left his home by car Thursday morning near Wilmington, with only a casual wave to the news media.
Obama is keeping quiet, too, but his staff in Chicago and party activists see Biden as addressing two of Obama's biggest weaknesses - his lack of experience, especially on world affairs, and his reluctance to attack his opponent.
