Here‘s a powerful thesis about red America and blue America. It isn’t about the north vs. the south. It isn’t about slave states vs. free states. It isn’t (primarily) about religion, or guns, or gay marriage. It’s about cities: an archipelago of blue cities in a sea of red suburbs and rural areas. It’s about the Urban Archipelago. Worth reading.
