The Washington Times reports on Michael Franc's "New Political Demography" research. Franc used IRS data to find the congressional districts in which the richest Americans live. And what do you know? As he wrote in the Financial Times in early November: "Democrats now control the majority of the nation's wealthiest congressional jurisdictions. More than half of the wealthiest households are concentrated in the 18 states where Democrats control both Senate seats." I take this as further evidence to support the thesis that today's politics primarily are driven by identity and cultural issues, not economic ones.
