That's "what would the Founders say," especially about religion and politics. Contrary to the claims of Medved, Land and their ilk, the Founders explicitly wanted a secular government.

This is from Federalist Paper # 10, by Madison, arguing for a secular national government:

"The influence of factious leaders may kindle a flame within their particular States but will be unable to spread a general conflagration through the other States. A religious sect may degenerate into a political faction in a part of the Confederacy; but the variety of sects dispersed over the entire face of it must secure the national councils against any sanger from that source."

This is from Federalist Paper # 69, by Hamilton, contrasting the role of the American President with the British Monarch. to the detriment of the Monarchy:

"The one has no particle of spiritual jurisdiction; the other is the supreme head and governor of the national church!"
