Hillary probably will be on something.
But the most interesting thing is going to be how they pick at each other's weaknesses.
You can be sure Hillary's camp has been brainstorming on things she can say to get Trump to blow his stack. Trump's Achilles heel does seem to be that if insulted, he will almost always take the bait. Trump has claimed that he hasn't practiced much for the debate; he seems to consider it beneath him, and doesn't want to come across rehearsed.
So what does Hillary have planned? What is Trump sensitive about? Will she talk about his businesses which have gone bankrupt? ("Donald, for someone who claims to be a successful businessman, you seem to have had an awful lot of businesses which have gone bankrupt. The Taj Mahal, Trump Air....")
Will she mention Trump University, possibly in a scathing aside? ("That sounds like something they'd teach at Trump University.")
Will she talk about his foundation? ("At least at the Clinton Foundation we never spent $6000 on an oil portrait of either Bill or me.")
Will she question his children's role in his campaign?
Will she mention that he had originally said he would spend a billion of his own money on his campaign but has only spent a small fraction of that? ("It makes people wonder if you're as rich as you claim.")
Will she make a remark about his appearance? ("I'm overweight and know it, and I never criticize anyone else's looks. Which is why I don't understand why someone as fat as you would feel as free as you do to criticize other people's appearance.") By mentioning her own weight, she would defuse his most stinging retort. And although it makes her look bad, it's almost sure to bring a response that would make him look even worse.
Will she refer, even obliquely, to his record with women? ("Judging a man like Mr. Putin is not as easy as judging the Miss Universe contest.")
Will Hillary reference Trump's lack of knowledge when it comes to foreign leaders and international politics? ("How can the Donald say he has a plan for resolving our difficulties in the Mideast when he doesn't even know the names of half the leaders over there?")
But Trump should have a counterpunch ready for this, as for many of these barbs. ("Where has all of your knowledge gotten us, Hillary? The Middle East is a far more dangerous place than when you started as Secretary of State. In fact, the entire world is. And it's because the Obama/Clinton team has been so weak.")
If she references his record with women, he can play his ace in the hole: Bill. ("But Hillary, you were in charge of the war room dealing with Bill's bimbo eruptions, as I think you called them. When Monica came forward, you said it was a vast right-wing conspiracy, and you called Monica a narcissistic loony tune. That doesn't speak very well of your record on feminism.")
Or, "Hillary, at least I made my money legitimately, not by taking back door bribes from countries which don't give women full rights and which prosecute gays."
Trump could point out that she would be nothing if not her husband. ("I'm a little surprised to hear you questioningly my business record given that you rode into politics on Bill's coattails.")
Or, "I'm just curious Hillary, when they talk about your platform, are they referring to your misguided attempts to side with criminals rather than cops, your burning desire to bring more potential terrorists into this country, or that stool you're standing on?" -- The Clinton camp has evidently requested a stool for her to stand on so that she looks taller.)
When she questions any of his views, he can reply, "I know it's complicated Hillary, but don't worry, I'll send you an email on it. Oh, wait a sec; maybe I shouldn't."
Of course, Trump doesn't want to appear to be too much of a bully, since he is dealing with a sick old woman. And no matter what insults he throws Hillary's way, the media will describe them as nasty and small-minded and a reminder that he doesn't have the temperament to be President. While simultaneously describing Hillary's insults to Trump as zingers that really hit the mark, or something to that effect.
So, maybe Trump should rein himself in. As Pat Buchanan recently said, all Trump really has to do to win the debate is to not appear the monster that the media has portrayed him as.
Refraining from hurling any insults be a tall order, though, especially if Hillary tries to provoke him.
Get your popcorn ready.
