"The family" by Jeff Sharlet
From here:
They are the Family—fundamentalism’s avant-garde, waging spiritual war in the halls of American power and around the globe. They consider themselves the new chosen, congressmen, generals, and foreign dictators who meet in confidential cells, to pray and plan for a “leadership led by God,†to be won not by force but through “quiet diplomacy.†Their base is a leafy estate overlooking the Potomac in Arlington, Virginia, and Jeff Sharlet is the only journalist to have written from inside its walls.
