The Republican Party has spent 30 years careering ever more deeply into ideological extremism, but one of the novel developments of the Obama years is its embrace of procedural extremism. The Republican fringe has evolved from being politically shrewd proponents of radical policy changes to a gang of saboteurs who would rather stop government from functioning at all. In this sense, their historical precedents are not so much the Gingrich revolutionaries, or even their tea-party selves of a few years ago; the movement is more like the radical left of the sixties, had it occupied a position of power in Congress. And so the terms we traditionally use to scold bad Congresses–partisanship, obstruction, gridlock–don’t come close to describing this situation. The hard right’s extremism has bent back upon itself, leaving an inscrutable void of paranoia and formless rage and twisting the Republican Party into a band of anarchists.
