We went through this last year. The complaint was that Bush had not publicly said the "J" word. Never mind that he referred to the Prince of Peace and that that is one of Jesus' names. No, he didn't actually say "Jesus."
There were a handful of malcontents who insisted that the Bush's were only pretending to be Christians in order to get the "fundie" vote.
At one point someone posted a picture of the Bushes walking out of church the previous Sunday, and one of the unappeasables basically said, "Yeah, but he's not carrying a Bible."
Sigh.
