Then maybe Trump should quit "riffing" until he can string a coherent sentence together.
Because Biden is over here giving solid speeches on how this moment reflects American history, while Trump is so completely confused (and, let's face it, that's being fucking generous) that he doesn't even know that Nicky Haley (who worked in his cabinet and who is running against him as a Republican) isn't Nancy Pelosi.
Am I cherry-picking? Has Trump said anything coherent in the last 12 months? On prompter or off. That's a serious question by the way.
Time to face the facts, Biden may be a bit old and doddering, but Trump is now straight-up demented.
It's no wonder he's afraid to debate, because he seems to have barely any idea what's even going on anymore. Why else do you think his handlers have him taking cognitive tests?
