Trump has frankly gotten embarrassed at every debate he's done, but the media handicaps him so hard that the narrative ends up being about everything his opponent does. So of course he's going to do the debate. He's going to say bat shit crazy things, he's going to lie, he's going to be cringe as fuck and he'll probably say a bunch of racist and sexist things.
And the next day all the media will talk about is the time Harris sneezed or slightly mispronounced some word or some shit.
It really isn't though. It is thermal noise.
