That map is not nearly as instructive as the county-by-county map which shows that the Democrat votes were concentrated in the nation's parasite centers (cities). So in general, those states with more and larger parasite centers went 'blue' (Democrat) while those states with less and smaller parasite centers went 'red' (Republican).
I wonder why most studies then show that the "parasite centers" actually send tax monies to the rural areas (i.e. pay more in taxes than get back from the gov)? There are tons of federal welfare farmers in rural areas.
