Very interesting analysis of the struggles within the GOP to stay as a meaningful party. From the article: "Put another way, there has been no basis for Republican unity in principle, except perhaps for a strong national defense. However, on matters of domestic policy, constitutional limitations on government power, economics, immigration, trade, civil liberties, individual rights...on just about everything you can name, Republicans are all over the map. There's no single principle, let alone broader political philosophy, that holds the party factions together."
