What’s up with the Republicans? Have they no sense that their policies have sent the country hurtling down the road to ruin? Are they so divorced from reality that in their delusionary state they honestly believe we need more of their tax cuts for the rich and their other forms of plutocratic irresponsibility, the very things that got us to this deplorable state?

The G.O.P.’s latest campaign is aimed at undermining President Obama’s effort to cope with the national economic emergency by attacking the spending in his stimulus package and repeating ad nauseam the Republican mantra for ever more tax cuts.

“Right now, given the concerns that we have over the size of this package and all the spending in this package, we don’t think it’s going to work,” said Representative John Boehner, an Ohio Republican who is House minority leader. Speaking on NBC’s “Meet the Press,” Mr. Boehner said of the plan: “Put me down in the ‘no’ column.”

If anything, the stimulus package is not large enough. Less than 24 hours after Mr. Boehner’s televised exercise in obstructionism, the heavy-equipment company Caterpillar announced that it was cutting 20,000 jobs, Sprint Nextel said it was eliminating 8,000, and Home Depot 7,000.
