Ambinder has gotten hold of a memo from Obama’s South Carolina Faith Team that, he thinks, is close to crossing the church-state separation line. It’s got an endorsement letter from Rep. James Clyburne. It says Obama’s people will be reading the stuff every Sunday and sharing with others. It says nothing about pastors doing endorsements from the pulpits. So yes, the campaign is working the faith-based crowd. But putting churches’ tax exemption in jeopardy? Not unless a pastor did something stupid.
