A highly recommended morning read: Thomas B. Edsall, The ‘Rotten Equilibrium’ of Republican Politics: Charlatans rise. Government falls.
Edsall presents data conclusively demonstrating that Republicans are now winning most of the economically backward states and districts while losing just about all the economically prosperous jurisdictions. These graphics tell the story.
He then considers at some length the implications of these data. For example, will it henceforth be in Republicans’ interest to prevent economic growth, lest the newly enriched become generous and therefore liberal?
