I imagine in terms of medical care access and affordability or welfare stimulus, practically negligible, but in terms of CDC funding, science literacy, public policy, and general preparedness, it would be a whole lot better put together.
So I'd say... 10% fewer deaths? 200K vs. 220K deaths sounds about right.
Ah, fair enough, I see what you mean about the masks. It would be better under not-Trump but I don't feel that the difference would be meaningful in any way
