text:  That's not the Joe Biden who showed up at the debate stage. He believes that he is the only person that can do it. The problem is after tonight, his party doesn't believe that. The hoarse voice, the open mouth look at the CNN debate that did nothing to allay voter concerns about his mental acuity and his stamina. And while Biden looked down, some Democrats told me that they are starting to look around to search for another candidate who could top the Democratic ticket.
