Ponnuru hopes Rand will run for president in 2016:

It’s not that I agree with his distinctive brand of libertarian conservatism — some of what’s distinctive about it I dislike — but it would be useful for his ideas to get a thorough debate, and for Republicans to figure out just where they stand nowadays on foreign policy and national security. We don’t have a great sense of how many Republican voters would fall into each camp if a primary campaign focused on it. For now, though, Republicans are moving in Paul’s direction — and the carping by John McCain and Lindsey Graham about that fact will not slow the tide.
