Once the cry and the cause of a generation of progressives to make America safer, fairer and cleaner, 'regulation' is now a dirty word in our politics. Even Democrats are quick to talk about cutting regulations Republicans hate them with - how to put it? - evangelical fervor.

Whether one believes or not, religion is as real a force in the life of the world as economics or politics, and it demands fair-minded attention. Even if you think the entire religious enterprise is at best misguided and at worst counterproductive, it remains vital, inspiring great good and, sometimes, great evil.

Without education, we are weaker economically. Without economic power, we are weaker in terms of national security. No great military power has ever remained so without great economic power.

The power of the American system of republicanism lies in its capacity to allow religious belief to be a competing, not a controlling, factor in American life.
