Transcript for Joe Biden Opens Up About the Chances of His Running for President
I would say 45, 50. Repor Ater: Li poce chasing whodly carjacked two cars driving on the wrong side of the road barreling through intersections nearly smashing into one car after another. Deputies finally sending the car spinning to The guy's running. No more than than maybe ten feet from me. Pistol in the air shooting. I thought he shot somebody. Took off and then an took off and chased him and went in the Chris' & Pitt's. Reporter: Dozens flocking out of the restaurant hands in the air. People would get out first and kept saying, I don't want to hurt nobody. He said, everybody go, everybody, get out. Exactly why they would want to be president and, two, they can look at the folks out there and say, I promise you, you have my whole heart, my whole soul, my energy and my passion to do this. And I'd be lying if I said that I knew I was there. Reporter: The vp paid an emotional tribute to his son beau who died of brain cancer in may. I was a hell of a success. My son was better than me and he was better than me in almost every way. Reporter: He hinted his grief may still hold him back from a 2016 run. Nobody has a right in my view to seek that office unless they're willing to give it 110% of who they are. I find myself and you understand, just sometimes it just sort of overwhelms you. Reporter: Despite Biden's uncertainty about running his support is on the rise. And many are pushing him to enter the race including Stephen Colbert. I think that your experience and your example of suffering and service is something that would be sorely missed in the race. Reporter: At one point during the interview the crowd there, the audience started chanting Biden's name as if encouraging him to run. George, Biden responded by saying, be careful what you wish for. This comes with a brand-new poll out now showing Hillary Clinton at new lows. Reporter: These are incredible Numbers. Take a look at this. Hillary Clinton now under 40% nationally, just 37%. Sanders second with 27 and Biden not even running yet at 20%. But maybe more interesting in this poll is the potential head-to-head matchups against republicans. Look at this, Hillary Clinton is now statistically tied with Jeb bush and Donald Trump in a hypothetical general election matchup. Joe Biden on the other hand, easily beats both Jeb bush and Donald Trump. I can assure you that Biden and his advisers will look at this poll very closely? That's a switch. Thanks very much.
