Joe Biden does not plan to participate in the first Democratic presidential debate Tuesday night, but the invitation remains open to the vice president should he make a last-minute decision to jump in the race and join his would-be Democratic rivals on the debate stage.<br />While all indications are that the reserved podium will go unused Tuesday night, the political world is watching in anticipation as the vice president continues a debate of his own, within the privacy of his Delaware home, in deliberating whether to mount a White House bid.<br />It had been expected that Biden would convene a family meeting to reach his final decision this weekend, which is why a pack of journalists have spent the weekend staking out the vice president's Delaware home, looking for any clue of the anticipated meeting.
