This is a win/win for Biden. If Trump pulls out of the debate, he looks like a coward. If he stays in it, all of America will once again see him as a raging lunatic. His poll numbers plummeted after the first debate. The same thing will happen again. Also, Biden won’t get flustered and can concentrate on his stuttering and lock down on being clear and concise.
And now on to the third debate, being questioned with his opponent directly in the room and not being allowed to shit his pants to create a distraction so the actual policy can be discussed by one candidate. I’ll be surprised if his campaign team actually lets him go – him showing up is more of a loss than screaming about everyone being out to get him and skipping.
