A combination of early presidential maneuvering and internal policy debate is feeding yet another iteration of that media perennial: the great Republican crackup. This time it’s tea party insurgents vs. get-along establishment fogies fighting principally over two things: (a) national security and (b) Obamacare.
(a) National security
Gov. Chris Christie recently challenged Sen. Rand Paul over his opposition to the National Security Agency (NSA) metadata program. Paul has also tangled with Sen. John McCain and other internationalists over drone warfare, democracy promotion and, more generally, intervention abroad.
So what else is new? The return of the most venerable strain of conservative foreign policy — isolationism — was utterly predictable. Isolationists dominated the party until Pearl Harbor and then acquiesced to an activist internationalism during the Cold War because of a fierce detestation of communism.
