Douthat says the Paulites need to build "a movement that will outlast the current political moment, and endure even when the incentives of partisanship cut a different way":
The real test will come when it’s a Republican president contemplating sending troops to Syria or when it’s a Republican economy that’s being goosed by the Fed’s monetary policy. I’m fairly confident that Rand Paul will raise his voice in criticism in those cases; I’m much less confident that there will be any kind of Paulista groundswell rising with him.
Larison is more optimistic about Paulism's future. I'm with Ross on this. The Paulites will be stiffed on foreign policy at every juncture.
