Here's an excellent chart that shows how Cuomo got COVID-19 under control in New York after Benedict-Donald refused to do his job and save American lives preparing us for this deadly pandemic. You can easily see the bulk of COVID-19 deaths occurred at the initial outbreak in March and April then began to taper off as mask mandates along with stay at home orders were implemented. No surprise as soon as it was business as usual again, we saw spikes occur in deaths, hospitalizations, and infections. That's what Republicans were demanding, so once again, the recent COVID explosion is all on them.
What do we take from this? Failed and neglectful GOP lack of leadership caused massive death, infections, and hospitalizations. Mask mandates and stay at home orders significantly reduced the number of deaths and new infections.
These are the facts and don't let any right wing propagandist try to tell you otherwise.
