BILL O'REILLY (HOST): Hillary Clinton is much more versed in policy. She can razzle-dazzle with facts and figures. Donald Trump is more of a generalist, big picture guy.

So, when it comes to specifics, you can expect more from Hillary Clinton on that front. But Talking Points believes it might not matter very much, because demeanor, the way the candidates handle themselves will be what many Americans are watching.

Example -- it would be unwise for Donald Trump to make faces as he sometimes did in the Republican debates. Remember that?

Also, it would be a major mistake for Mrs. Clinton to sound shrill, or to call Trump names. That would erode her status as a public figure.

[...]

O'REILLY: But again, Americans want authoritative problem solvers, not foolish game players. The demeanor factor -- the demeanor factor, extremely important in this debate tonight.
