The WaPo is confused:
Bush has said many times that he is a Christian, believes in the power of prayer and considers himself a “lowly sinner.” But White House aides said they do not know whether the president believes that: the Bible is without error; the theory of evolution is true; homosexuality is a sinful choice; only Christians will go to heaven; support for Israel is a biblical imperative; or the war in Iraq is part of God’s plan.
Some political analysts think there is a shrewd calculation behind these ambiguities. By using such phrases as the “culture of life,” Bush signals to evangelical Protestants and conservative Catholics that he is with them, while he avoids taking explicit stands that might alienate other voters or alarm foreign leaders. Bush and his chief speechwriter, Michael J. Gerson, are “very gifted at crafting references that religious insiders will understand and outsiders may not,” said the Rev. Jim Wallis, editor of the evangelical journal Sojourners.
This president is no more religous than my cat. He realized during his daddy’s failed presidential campaign that if you claim to be born again and use the right fundie buzzwords the skypilot crowd will back you every time.
