R.R. Reno on Rick Santorum and the liberal bulldozer:

Rick Santorum was impossible thirty years ago. If Rip van Winkle woke up today he would be dumbfounded. How could such an overtly religious and socially conservative politician have so much traction on the national scene?

The answer comes from the Left. Since the Sixties our liberal elites have become increasingly anti-religious, increasingly opposed to traditional moral norms, and increasingly aggressive. As a result they have made our national politics much more extreme.
