COMMENTARY: Paul establishing lead over Cruz in battle for Reagan's legacy

It’s on! Ostensible allies for the last couple years, Sens. Ted Cruz (R-Texas) and Rand Paul (R-Ky.) have commenced the battle for the unofficial title of conservative front-runner. That’s no surprise, but what is remarkable is their choice of weapons: foreign policy. For the last several years, there has been a lot of overblown hype about how the GOP, particularly the party base, is becoming isolationist. So it’s interesting that Cruz would seek to get to Paul’s right on the issue.
