"A Domestic Cuban Missile Crisis"

"The debt ceiling turns out to be unexploded ordnance lying around the American form of government. Only custom or moral compunction stops the opposition party from using it to nullify the president’s powers, or, for that matter, the president from using it to nullify Congress’s. (Obama could, theoretically, threaten to veto a debt ceiling hike unless Congress attaches it to the creation of single-payer health insurance.) To weaponize the debt ceiling, you must be willing to inflict harm on millions of innocent people. It is a shockingly powerful self-destruct button built into our very system of government, but only useful for the most ideologically hardened or borderline sociopathic. But it turns out to be the perfect tool for the contemporary GOP: a party large enough to control a chamber of Congress yet too small to win the presidency, and infused with a dangerous, millenarian combination of overheated Randian paranoia and fully justified fear of adverse demographic trends."

Jonathan Chait in New York explains the stakes of the current standoff.
