For those of you champing at the bit for something pertinent to read, may we offer what was earlier suggested by David Little for the Forum committee's research:
Thomas Franck, What's the Matter with Kansas? How Conservatives Won the Heart of America. Chapters 3, 6, 9, 10, and 11 all concern religion, but the whole book could be read to appreciate the force of the general argument (very relevant to what we are currently experiencing in this country).
Jim Wallis, God's Politics (especially chapter 9, "Dangerous Religion: The Theology of Empire").
