Will the Christianists break away from the Republicans?
Of course, I'd love to see the the Christianists get their own party. I think this would be an enormously healthy development for our country. It would free the Republicans from the influence of the religious right, allowing them to become something else (maybe they'd just end up as fear-mongering, xenophobic, cronyist hacks, but that's better than fear-mongering xenophobic, cronyist hacks who are apocalyptic, puritanical, fundamentalists to boot.) This Christianist third party could ally with the Greens, the Reform Party, and other groups to push for reforms to break the lock of the two party system. And America would be able to see the Christian right wing in all its glory, unmoderated by the other elements in the Republican coalition. They'd get elected in some places at the local and state level, and probably make themselves look like total asses.
And of course, they'd split the votes that currently go to Republicans and throw the election to Democrats in a landslide. (Unless they managed to get those multi-party reforms in place before making their run.)
