Not sure about this, but Christianity doesn't even really lend itself well as a political system. Nowhere in the Bible does it advocate a theocracy. It says to move to the hinterlands of nations and empires and render unto Caeser and all that. It's more like Quakers, Mennonites, Amish and monasteries. Withdrawal from nations and kings and governments, not seizing control over them.
That depends on what you specifically call "Christianity" really. The teachings of Jesus don't exactly advocate nationalism or seizing political control (although he didn't exactly advocate non-intervention either, all that "And I will come with a sword" business). The Old Testament though, for all Judeo-Christian-Islamic societies, does have quite a few politically motivated passages and notes on laws. Deuteronomy especially is full of weirdly explicit rules on how an Abrahamic society is supposed to govern itself, along with the goofy grab bag from Leviticus and Exodus. Essentially none of which, it should be noted, are reflected in the standing laws of any ostensibly "Christian" nation.
So it really baffles me how Republicans can even really represent a coherant philosophy. Freedom and Theocracy? Capitalism and Interventionism? That isn't Christianity, it's not even logical, ffs.
It's not Christian per se, no. It's hard to say that it explicitly violates it, more than any political power that claims to be guided by Christianity ever has. Logical is a different matter. It all makes perfect sense if you believe that a storybook interpretation of American history gives it a manifest right to impose whatever we're calling American Values this week on all people of the world. It's all about definitions.
Anyway, I'll throw a note into the OP about the Rick Santorum rolling up three meaningless elections. What's next, Maine? Pfft. I can't remember if their votes count either. Then the Northern Marianas Islands, because territories (did you remember that America has territories?) don't count for the Electoral College but they do count for party nominations. And then
finally Arizona and Michigan a whopping 20 days from now. And I think they're still part of the schedule of states penalized by the party for having their primaries before March.
