Point out the limitations of analyzing voting data by county rather than by population, and describe how this could lead to misleading conclusions about voter preferences.
Then you should look at a map showing all of red and blue America not by counties, which don't vote, but by people, who do. America was more blue than red in presidential voting, just not in the right states. Some of the largest counties by land area voted Republican and are red but the number of actual people in them pales in comparison to the largest counties by population that voted Democratic but are smaller in square miles. So your looking at a map of red and blue counties is entirely misleading as to the actual preference of the voters. The vast majority of living, breathing human beings, not land, voted against the buffoon currently in the White House.
