On the question of that anti-Bachmann hit piece in the New Yorker, don't miss this from philosopher Douglas Groothuis:
Those who tar and feather "dominionists" are confusing their readers by conflating Rushdoony's reconstructionism with the thinking of Schaeffer and Pearcey. Worse yet, Lizza and company may believe that any Christian influence in politics is dangerous and un-American. If so, they should reread and ponder the First Amendment's guarantee of religious freedom and the freedom of speech. Christians are free to be active members in the public square -- along with those of other religions or none. Erecting "dominionist" straw men does nothing to advance this noble cause of freedom.
