I know we're in like, mystical "follow the science" land, but any study on this matter can really only make projections based on a model.
It certainly can't say what Biden would have called a "reasonable response" at the time, whether he would have followed through on it, etc. We actually know what Biden was saying to do in the early days of the pandemic, and Trump's earliest actions were roundly criticized by Democrats.
My theory is that if Trump had come out hard for lockdown early on, Republicans would be pro-lockdown and Democrats would be anti-lockdown. I view the partisan divide on COVID handling as...well, purely partisan.
