A Coalition of the Heartless, the Clueless and the Confused.

Paul Krugman gets it right again.

There was a time when everyone took it for granted that unemployment insurance, which normally terminates after 26 weeks, would be extended in times of persistent joblessness. It was, most people agreed, the decent thing to do.

But that was then. Today, American workers face the worst job market since the Great Depression, with five job seekers for every job opening, with the average spell of unemployment now at 35 weeks. Yet the Senate went home for the holiday weekend without extending benefits. How was that possible?

The answer is that we’re facing a coalition of the heartless, the clueless and the confused. Nothing can be done about the first group, and probably not much about the second. But maybe it’s possible to clear up some of the confusion.

By the heartless, I mean Republicans who have made the cynical calculation that blocking anything President Obama tries to do — including, or perhaps especially, anything that might alleviate the nation’s economic pain — improves their chances in the midterm elections. Don’t pretend to be shocked: you know they’re out there, and make up a large share of the G.O.P. caucus.

By the clueless I mean people like Sharron Angle, the Republican candidate for senator from Nevada, who has repeatedly insisted that the unemployed are deliberately choosing to stay jobless, so that they can keep collecting benefits. A sample remark: “You can make more money on unemployment than you can going down and getting one of those jobs that is an honest job but it doesn’t pay as much. We’ve put in so much entitlement into our government that we really have spoiled our citizenry.”
