DAN KLAIDMAN: Donald Trump is pretty far behind in this race, both in national polls and in the battleground states. So it's really going to be up to him to have to sort of shake this thing up and change the dynamic. So what I'm going to be looking for is to see how Joe Biden handles Trump.

First of all, he can't make any big mistakes. He has to seem competent, fluent in his language which hasn't always been easy for him during these debates. And, you know, I think what he needs to do is come off as a plausible president, and if he does that I think he's going to do well. Expectations are low for him, partly because the Trump campaign and President Trump himself have set those expectations very low.

One thing that I'm going to be looking for is to see how he handles the personal attacks that we know will be coming at him from President Trump because that's the way President Trump debates. And there have been a lot of people who've said he shouldn't take the bait. He'll get rattled. It's not-- anger is not his best side. I agree with all of that.

I also, though, think that there may be a moment for a kind-- some sort of-- a flash of controlled anger. If Trump comes after his sons, either Hunter or the late Beau Biden, you know, I think if-- if Biden shows a little bit of anger there in defense of his own children that might actually help him. It will energize Democrats. It might even get some of the fence sitters off of-- off of the fence. But it but it has to be controlled.
