Transcript for Democratic Showdown: Hillary Clinton in Preparation Mode for Debate
All right, thank you. The showdown in Vegas. What could be a critical moment for Hillary Clinton. Tonight, we are learning what she and her team are preparing. She will be on the stage with her democratic opponents. Of course, the wild card remains Joe Biden. Will he run? The extra podium is ready. The decision will not come in time for that. Tonight, what we learned on the Biden front. And even president Obama weighing in on Clinton's private e-mail server. Cecilia Vega has the story. Reporter: Hillary Clinton deep in debate prep behind closed doors, but tonight all eyes on the one person who won't be anywhere near that stage. Joe Biden spending the weekend in Delaware with family. Sprinting at his granddaughter's cross country meet. But dodging questions about whether he plans to run for the white house. Get out of my way, will you? Reporter: President Obama weighing in on 60 minutes with nothing but praise for Biden. I think Joe will go down as one of the finest vice presidents in history, and one of the more consequential. I think he has done great work. Reporter: The president won't say whether Biden should enter the race, but has some strong words for Clinton and her troubles with that private email server. I don't think it posed a national security problem. She made a mistake. She has acknowledged it. I do think that the way it's been ginned-up is in part because of politics. And I think she'd be the first to acknowledge that maybe she could have handled the original decision better and the disclosures more quickly. Reporter: Still, national polls show Clinton with a commanding lead, and Biden trailing far behind. But he could still cost her crucial votes in Iowa and new Hampshire, where she's locked in a battle with Bernie sanders. If she can weather that storm, new polls out today show her way ahead in the next two states. A 25 point lead in south Carolina and a 16 point too. This flight in Las Vegas, aborting takeoff after an engine fire. Passengers rushed off there too. David Kerley leads off us
