A Democratic president begins a new term in the White House. Two years later, America votes a cadre of aggressive conservatives into Congress, loaded for bear. At first the Republican establishment, thrilled to have the Democrats on the run, puts its wariness about the fire-breathers aside. Within a few years, though, the new guys throw out all the old rules of consensus and compromise, and the establishment shows signs of buyer’s remorse. One of the new conservatives, a bulky, take-no-prisoners senator who sees socialist quislings everywhere, takes control of the agenda and threatens to drive the GOP into the ground.
