Empty Vessel?

Daniel Drezner wonders if the Republicans in the age of Rush have anything to offer on foreign policy:

The concept of a “loyal opposition” is a difficult one to straddle. On the one hand, it is vital for Americans to be exposed to contrasting takes on the best way to advance American interests. Opposition forces the current leadership to defend and articulate their preferred course of action. On the other hand, opposition based on the principles of Joe the Plumber is simply not an opposition that can be taken seriously. Let’s hope the GOP can form a viable counterweight so that more foreign-policy opinions and valuable debates become a reality. Peanut-gallery snarkery will serve no one.
