Even N95 masks have been ineffective at blocking COVID since Delta variant. With the original COVID they weren't great but at least the effectiveness was measurable. Then the first variants started to pop up and the measured effectiveness was cut in half, causing the whole double masking crusade. By Delta and after, all paper masks did was signal what team you are on. Going in to the election, some are going to wear their Trump shirts and others are going to wear their masks. I'll let people do what people do, but I'm against either mandates for Trump shirts or mandates for COVID masks.
