Chet, I think it is spreading more and more because of Trump. Look at the Trumpers, they refuse to use face covering and "party" a lot and even are going to an large "bikers" festival, likely without "face covering" in an State (S.Dakota) which is run by Trumpers.
So my hope is that more Trump voters are affected than the non-Trump voters; it already showed during his rally in Oklahoma which killed an "black" buddy of Trump and quite a few others as well security guards.
