Via Paul Caron comes this story from USA Today about “Pulpit Freedom Sunday,” an effort by 100 preachers around the country to challenge IRS rules that threaten churches with the loss of nonprofit status if they endorse candidates. The pastors will explicitly urge their congregations to support specific candidates in their sermons today. Given the involvement of the Alliance Defense Fund, I suspect most of the endorsed candidates will be conservative Republicans. Meanwhile, Caron also notes that the Obama Administration’s Office of Faith-based Initiatives is urging religious leaders to become “validators” of health care reform.
