AOC is, of course, a moron, but I don't believe her behaviour was especially careless. The Omicron variant is simply so transmissible that all of the measures the public is ordered to, or recommended to follow are just not accomplishing much. Fortunately, Omicron is also not very serious (unless you already have significant health problems).
Perhaps if enough politicians were to contract Covid these points might penetrate their thick skulls. As result, I would like ALL politicians who do not have any signficant co-morbidities to contract Covid as soon as possible. Follow AOC's lead. I think that's the only hope that the public has to get back on a path to normal economic and social activity.
