"Yes, the debate was comfortable to Democrats concerned about their front-runner, but it should also have been worrisome to Democrats concerned about their bench."

"'The fact she did well should surprise no one,' a Biden activist told me. 'If she didn’t do well against those guys, then God help our party.” If something serious were to happen to Clinton — self-inflicted or not — the party would be entering a presidential race on favorable terrain but with a substantial talent problem. Martin O’Malley presented no rationale for a campaign; Jim Webb sounded bitter and bizarre; Lincoln Chafee at times appeared confused why he was even onstage. Sanders electrified his core supporters but didn’t suggest any newfound ability to sell his far-left platform to the general public. In a scenario where a Clinton campaign implodes, Democrats will again be desperate for a new candidate and will again review the options. Al Gore’s name will be floated. 'Al Gore is doing nothing,' said a Democrat who sits on a board with him. Same with John Kerry. 'John has not given the slightest indication he would do this,' Bob Shrum, who ran Kerry’s 2004 campaign, told me. What will be real is Biden."
