Personally, I think there would've been less death, but not dramatically less.
At the end of the day, Republicans and Dems are both capitalist and answer to the same overlords, so they still wouldn't have done what actually needed to be done to properly handle it (AKA do what China did).
Despite the obvious difference in healthcare systems, I think the U.K. could serve as an instructive example of another country I with a center-right government that “believes the science”’ (that is albeit still to the left of the Democrats).
Fauci probably would have still told people not to wear masks at the outset, the conspiracy theories would’ve been even worse, there would be no furlough payments…it’s entirely possible the death rate could be even higher than it is now, too.
