So close to that presidential microphone . . . yet so far away. As President Barack Obama delivered his 2,000-word inaugural address outside the Capitol last month, his chief governing partner, Vice President Joe Biden, looked on from his chair just to the left, always the loyal and supportive cheerleader.

But for Biden, who mounted two unsuccessful bids for the White House, Inauguration Day served as another reminder of all that he has achieved and what has eluded him after 40 years in public life. And his prominent role in so many of the administration's recent high-profile initiatives has raised questions about whether Biden has plans to be in Obama's place on the podium four years from now.

But Biden, 70, was not complaining. Speaking briefly at a postinauguration lunch in the Capitol, Biden told the assembled power brokers, including former Presidents Bill Clinton and Jimmy Carter, that he was thankful.
