Well, it honestly is.
If he had reacted sooner with respect to coronavirus and hadn't dismantled the pandemic response teams...or if he had just READ the documents produced by the pandemic response teams...he might have had us quarantined a bit earlier, been able to stockpile ventilators a bit earlier, and subsequently reduced the number of cases by around half.
This would possibly mean our curve would have followed that of S. Korea instead of the upward trajectory we're on now.
His inaction will be directly responsible for anything covid related from this point on. So, technically, you're 100% correct.
At least you're coming around to blaming Trump for something instead of trying to make excuses for him...that's a good first step.
