I hate to be this cynical, but there is nothing in the data to justify masking young kids. Which means that there is no change in the pandemic, or the campaign to vaccinate the public, that can cause school districts or the CDC to relent.
But I can’t help but think that an adverse result for Gavin Newsom in the California recall process would immediately send a signal through the nervous system of the ruling class, and inspire a wave of relaxations on mask mandates for kids.
