The term "Two Americas" was coined by the great slip-and-fall Senator from North Carolina, John Edwards. We can now see graphic proof of his idea in this county-by-county electoral map from the recent presidential election. The map is the work of Mark Newman. Notice how the blue is mostly limited to urban areas of high population density: the northeast, the west coast, the tip of Florida, the upper midwest (Chicago, etc.) This is one America, comprised of upper middle class and upper class white liberal elites, service union members, city dwellers who do not depend on cars, the entertainment industry, the pornography industry, etc. The second America, the Red America, is the rest of us. We are also know as bitter clingers, or, in the olden days, the silent majority.
(Please also notice the correct use of the word comprised.)
