Racist, sexist->> After months of naked vitriol and name calling, Monday night's lead off debate posing the test of a lifetime for Hilary Clinton and Donald Trump, two of the most divisive candidates ever going at it for the first time on the same stage.
>> You're watching the two trains about to collide.>> Report Steve Holland says, with the polls close it all comes down to how the well prepared Clinton handles volatile Trump with everything on the line.>> Hillary Clinton and her aids are preparing for two Donald Trumps, a disciplined Trump and a free-wheeling, out of control Trump.
>> I'd like to punch him in the face, I'll tell ya.>> It makes it really hard to game out exactly how to handle it. We should expect her to fact check him, to say that his tax plan, a lot of his plans simply don't add up. She's gonna be a tough vote.
>> Having burned through the crowded GOP primary with brutal putdowns, Trump has proven he's dangerous, but Monday will demand much more.>> Trump needs to prove that Americans can view him as a credible president. He will be required to talk in a lot more detail about policy and issues than he has in the past, and there's a lot that Americans don't like about Donald Trump.
But this is chance to say, hey, you know what, you can trust me in this job. He can credibly say he's a change agent. Hillary Clinton will have a hard time pulling that off because she's basically running to succeed President Barack Obama. The election could hinge on this debate.
Our polling suggests that as much as 20% of the electorate is not sure who to vote for. Undecided voters could change this race dramatically, depending on how they tilt. And so, that's what's at stake here.
