Btw, I actually know why Trump’s campaign is trying make cognitive ability an issue. They know Joe Biden is prone to making gaffes as well as sometimes occasionally stumbling over a word due to his stutter. They figure it’s only a matter of time before Joe makes a gaffe and they want to be able to “spin” that as mental decline. That’s why they are frustrated as hell that Joe Biden isn’t out there 24x7. They want a gaffe to pounce on. A big problem with their strategy is they have made a weakness of Trump’s (cognitive ability) their weapon against Biden, and no matter how much they wish it were true, Biden isn’t suffering from dementia. But Trump is—or at least something which is causing a mental decline—and it is getting worse...everyone can see it. I think this strategy will backfire.
Biden doesn't have to say anything. T is destroying himself.
