Paul Krugman: Getting to Crazy

There aren’t many positive aspects to the looming possibility of a U.S. debt default. But there has been, I have to admit, an element of comic relief — of the black-humor variety — in the spectacle of so many people who have been in denial suddenly waking up and smelling the crazy.

A number of commentators seem shocked at how unreasonable Republicans are being. “Has the G.O.P. gone insane?” they ask.

Why, yes, it has. But this isn’t something that just happened, it’s the culmination of a process that has been going on for decades. Anyone surprised by the extremism and irresponsibility now on display either hasn’t been paying attention, or has been deliberately turning a blind eye.
