Doug Groothuis, The Constructive Curmudgeon, points us to his article, Michele Bachmann and Dominionism Paranoia.  Excerpt:

There is a buzz in the political beehive about the dark dangers of Bachmann's association with "dominionism"—a fundamentalist movement heaven-bent on imposing a hellish theocracy on America. In the August 15 issue of The New Yorker, Ryan Lizza asserts that Bachmann has been ideologically shaped by "exotic" thinkers of the dominionist stripe who pose a threat to our secular political institutions. The piece—and much of the subsequent media reaction—is a calamity of confusion, conflation, and obfuscation.

Leftists are astonishingly bad at threat assessment.  To reverse the scriptural phrase, they will swallow  the imaginary gnat of 'theocracy' while straining at  the all-too-real camel of  Islamo-terrorism.
