The difficulty here is that I honestly don't think that recommending masks during a once-in-a-lifetime pandemic is some sign that things have gone crazy left politically. What you seem to be telling me is that President Clinton would have been an idiot rather than that he'd be more center.
What proof or evidence is there that this was a once in a lifetime pandemic? It goes both ways and nobody truly knows, we can only guess.
Masking if it's clearly useful enough isn't so much the problem in a bubble I'd assume, but more so it's the question of how useful the types were, how useful they were for everyone, and why no money for (better masks) if there was a definite need, with all the money that was thrown around?
I would also guess, in a world where every type of new safety measure tends to become the norm, like our new normal, it's not ridiculous to believe that people will assume the next illness, regardless of severity, and so on, will automatically lead to masking up. Again, nobody truly knows.
I wouldn't say Clinton was an idiot overall. He was a relatively decent President in comparison. There was the whole Monica thing which wasn't exactly handled professionally, and not professional to begin with, but that's getting way off topic.
