Advocating an outdoor mask mandate will only be popular in deep blue urban areas. Everywhere where there is enough space to be outdoors a lot of the time without being within 50 much less 6 feet of anyone, the notion of having to wear a mask just because you left your house is rightly anathema. Enclosed public places like stores, restaurants (when not actually eating), classrooms, offices,... sure, but that's not what Biden is calling for, he's calling for the rubbish deSanto was backed into in Florida, where for a long time they had a mask mandate in public buildings, but now the cops will harass you if you're sitting maskless in the middle of a park, the only person in the park until the cops turned up.
