One of several things I learned from Matt Continetti’s profile of Rand Paul, Kentucky’s libertarian junior senator: Paul is a savvy political entrepreneur, primed to have a far more significant legislative impact than his father.

The profile is also a reminder that the Paul movement was more than a fringe phenomenon. It has already shaped the Republican coalition in a number of ways, e.g., by making the conversation on civil liberties and national security within the tent less monolithic, and by sparking a revival of pre-supply-side conservative economic thinking.
