Michelle Goldberg diagnoses the core philosophy of Perry and Bachmann: the most radical theocratic politics in the West. And if you haven't read Ryan Lizza's extraordinary piece on Bachmann's explicitly celebrated theological worldview, please do. Money quote:

For believers in Dominionism, rule by non-Christians is a sort of sacrilege—which explains, in part, the theological fury that has accompanied the election of our last two Democratic presidents. “Christians have an obligation, a mandate, a commission, a holy responsibility to reclaim the land for Jesus Christ—to have dominion in civil structures, just as in every other aspect of life and godliness,” wrote George Grant, the former executive director of Coral Ridge Ministries, which has since changed its name to Truth in Action Ministries. “But it is dominion we are after. Not just a voice … It is dominion we are after. Not just equal time … World conquest.”

But both Clinton and Obama are Christians. My own view is that it is the very sincerity and clarity of Obama's Christianity – laid bare most pellucidly in his Neiburhian Nobel speech – that drives the Christianists nuts. It is so alien to them that they have to believe he is a Muslim.
