The problem with the Republicans' attacks on Joe is that any negative they throw at Biden, the same can be said of Trump but 10x worse. And I have a hunch that there's precious few undecideds left, and that most voters have already decided, anyway. Pushing a narrative like "Sleepy Joe is getting forgetful" isn't going to convince people to vote for the "Man Woman Person Camera TV" guy at this point.
