>> We've come to a rendezvous for destiny.>> She's prepared to be president and she's prepared to be Commander-in-Chief.>> First, do no harm, that tops the checklist for VP rivals Mike Pence and Tim Kaine.>> Going into their one and only debate class Tuesday night at Virginia's Longwood University.
Campaign reporter Jim Oliphant.>> Probably the most famous moment in Vice Presidential debate history if there is such a thing, was Lloyd Bentsen's take down of Dan Quayle in 1988.>> I have as much experience in the Congress as Jack Kennedy did.>> I served with Jack Kennedy, I knew Jack Kennedy, Jack Kennedy was a friend of mine.
Senator, you are no Jack Kennedy.
>> It wasn't just the put down, but Quayle's deer in the headlights reaction, feeding a narrative he was too green for the job. Bush went on to win but Quayle never recovered.>> If you wanna say Dan Quayle made a mistake, it was making it about him.
And his resume and who he was, that's not what you are suppose to do up there. It's suppose to be about the top of the ticket. So, Mike Pence has to make it not about Pence, it's about Donald Trump. And similarly Tim Kaine, it's about Hillary Clinton's record, it's not about about Tim Kaine.
>> The number twos have to show that depth and savvy to be credible standins for Hillary Clinton and Donald Trump. Pence has to make Trump viable for establishment Republicans, while Kaine has to cajole white men like him to back Clinton. But above all, their job is to not do anything diverting attention from the top of the ticket.
