Of course there are going to be debates. Choosing not to debate would guarantee a loss for that candidate.
Now, once they're on stage, Trump is going to be far more poised than Biden. Does Trump say stupid things sometimes? Sure he does. But at least you can understand him. Biden comes across as a doddering old fool. He mumbles and slurs his words and, let's face it, there's no shortage of evidence out there which shows how badly he loses focus.
Between Trump and Biden, the choice for the world stage is clear. We cannot afford to have someone out there, representing us, who can't even properly quote a part of the Declaration of Independence which, back when I was a kid, we were taught (and I remember it to this day) in school:
The man is falling into a dementia wasteland, but his handlers can't afford to get him any treatment because it would end his campaign if that ever got out (and you know it would).
The debates will signal the end of Joe Biden's political career and will solidify a Trump presidency for another four years...
