It happened again because of course it happened again. The latest example of COVID hypocrisy, if you have enough hard-drive space to keep track, is a viral video of President Biden traipsing through a ritzy DC eatery with no mask, in defiance of the city’s strict rules. In Chicago, Mayor Lori Lightfoot was photographed at a basketball game, the only bare face in a sea of muzzled fans.

This kind of thing has been so common that it is hard to stay outraged, even though we should.

But there is another, deeper question at play here. Why won’t the Centers for Disease Control and Prevention update its masking guidance as vaccinations increase, case numbers diminish and politicians, among pretty much everyone else, ignore it across the nation?

The CDC website says that “If you are fully vaccinated, to maximize protection from the Delta variant, and prevent possibly spreading it to others, wear a mask indoors in public, if you are in an area of substantial or high transmission.” A handy map shows the location of these areas — it’s basically the entirety of the United States. This guidance is vague, and not followed by massive swaths of the nation.
