IF he even does it, Biden will get NUKED in the debate. And then the media will pile on Trump for being “mean” to him. And they will do it, acting like Demonrats are never mean. See: Kavanaugh, Thomas, Bork, etc...
Trump’s win will be bigger than last time.
There’s such a low expectation for Biden that if he shows up, doesn’t wet his pants, and keeps his gaffes under 50% of what he says - he looks like a champ.
There is a real probability that something happens inmthe next few days that biden uses as an excuse to not debate.
I just hope challenges DJT to a pushup contest.
