Yesterday every single Republican senator voted to shut down the U.S. government and provoke a global financial crisis.
Of course, they claimed otherwise; Mitch McConnell, the Senate minority leader, portrayed the vote against raising the debt limit as a test of Democrats’ ability to govern, and some of his colleagues claimed to be taking a stand for fiscal responsibility. But everyone involved understood that this was an act of political sabotage. And the terrible thing is that it might work.
