David Domke and Kevin Coe have teamed up to publish a new book, The God Strategy: How Religion Became a Political Weapon in America. The book highlights the increase of religious rhetoric in recent years.
"On average, presidents from Franklin Roosevelt to Jimmy Carter mentioned God in less than half of their major addresses. Put another way, more often than not presidents during these years made no mention of God in important speeches. Reagan, Bush, Clinton, and Bush (through year six) all did so in more than 90% of theirs."
