American Revolution Blog:

Check out this group blog by an intellectually diverse, but right of center group with an interest in the history of the American Founding. I've participated in a number of different discussion threads there and they have a genuine interest in the question of the religion of America's key Founders. See their most recent one on James Madison which follows the Stephen Waldman/David Holmes/Gregg Frazer (and Jon Rowe) view that America's key Founders were neither Christians nor Deists but somewhere in between.
