It's not John Hagee or Rod Parsley. It's Mike Huckabee:

Some U.S. Christians are not reconciled to McCain's candidacy but instead regard the prospective presidency of Barack Obama in the nature of a biblical plague visited upon a sinful people. These militants look at former Baptist preacher Huckabee as "God's candidate" for president in 2012. Whether they can be written off as merely a troublesome fringe group depends on Huckabee's course.

McCain and Huckabee were friendly rivals in this year's Republican competition, sharing contempt for Mitt Romney. Indeed, McCain would not be where he is today had Huckabee not mobilized born-again voters to upset Romney in the Iowa caucuses. All of Romney's efforts to overtake McCain in conservative Southern state primaries were stifled by Huckabee's success in those contests. Huckabee quickly endorsed McCain once he clinched the nomination. They bonded publicly in Little Rock on April 24 during McCain's tour.

Nevertheless, the word is that some evangelicals dispute Huckabee's support. One experienced, credible activist in Christian politics who would not let his name be used told me that Huckabee, in personal conversation with him, had embraced the concept that an Obama presidency might be what the American people deserve. That fits what has largely been a fringe position among evangelicals: that the pain of an Obama presidency is in keeping with the Bible's prophecy.

I'd want way more information than a single Bob Novak column before venturing any opinions as to how this might play out. Could be a major or minor civil war within the Republican/Evangelical nexus - or it could amount to a hill of beans. We'll see.

But I do know what this means:

Even taking Huckabee's professions of support for McCain at face value, he is not leaving politics for the lecture circuit. He has formed the Huck PAC to back Republican candidates, his supporters have established a Web site (Huck4America.com), and Huckabee backers are behind the Government Is Not God PAC, which aims to discourage McCain from naming Romney as his vice president.

It means sign the petition. A politician with ambitions is a politician we can pressure.
