The CDC changed its social distance guidelines, and I have no doubt the researchers found what they found. However, the reason they found it was more about keeping a campaign promise rather than keeping people safe.
I like president Biden, but the only reason we are making this change is to keep his campaign promise to open more schools, and that with light finally at the end of the tunnel is inexcusable.
The study sited has so many caveats you could drive a truck through it, and it is hardly representative of the country. They chose their set to study because they already had a conclusion they wanted to meet.

That might be impressive if it was from all across the country in districts big and small, rural and urban, but it wasn't. It was just from Massachusetts, and as you will see, it is only about half of this one safe.
This is Massachusetts.
