The Past vs the Present

Peggy Noonan’s take on the GOP race:

Mr. McCain is in the middle of a shift. Previous strategy: I’m John McCain and you know me, we’ve traveled through history together. New strategy: I’m the old vet who fought on the front lines of the Reagan-era front, and I am about to take on the mantle of the essentials of conservatism—lower spending, smaller government, strong in the world. He is going to strike the great Reagan gong, not in a way that is new but in a way that is new for him…

Do conservatives take inspiration from Mr. Romney’s newness? Or do they take comfort and security from Mr. McCain’s rugged ability to endure, and to remind?
