I wouldn't count on it. She has been through debates, the DNC convention and in the public eye for decades. Trump is not much of a debater as we know. All Hillary has to do is rope-a -dope. So I think the debates will be a bunch of nothing and what we've already heard from both of them. The only way that might change would be if the format were changed to allow a one on one free-for-all but I don't see that happening. The debates are rigged.
A loud noise, a flash of light, or an unusual sign or banner should be enough to vaporlock Hillary, at least until she gets her pharmaceutical fix from her handler.
