Life is filled with dangers, but there is one danger that Professor Mark Silk need never fear: being charged as an example of the adage that a little learning is a dangerous thing. Silk has been studying the role of religion in American politics in greater depth and with greater precision than almost any acdemic I can think of. He has the capacity, which I utterly lack, of being patient enough to pore over the cross-tabs on polling data to ferret out key kernals of information. And so, readers are advised to go to his blog Spiritual Politcs and see some of his revent posts on the role of religion in the NH primary, good news for Romney in polling of evangelicals in SC, and Silk's takedown of a recent their put forth by a less learned member of the press corps at the Washington Post. Good, good stuff.
