I agree.
In the old days, SNL would have a field day with stuff like this. But even if late night comedy goes easy on Joe, enough people are aware of the possibility that his brain isn’t quite right. Now, in a debate, if he says something ridiculous or has a brain freeze, or whatever, it will just validate what a lot of people are already worrying about.
From the way he’s been portrayed in skits, Biden wasn’t SNL’s first choice of candidate. They’ll probably go easier on him now though that he’s the likely nomineee.
