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).
We would have reacted more quickly and competently but it wouldn't have changed much, since we never would have done the lockdown/testing/border control necessary to get the virus under control, and chuds will be chuds.
