It wasn’t until Hurricane Katrina  when the heckuva job done by the man of whom Ms. Noonan said, “if there’s a fire on the block, he’ll run out and help” revealed the true costs of obliviousness  that the cult began to fade.

What’s more, the politics of stupidity didn’t just appeal to the poorly informed. Bear in mind that members of the political and media elites were more pro-war than the public at large in the fall of 2002, even though the flimsiness of the case for invading Iraq should have been even more obvious to those paying close attention to the issue than it was to the average voter.

Why were the elite so hawkish? Well, I heard a number of people express privately the argument that some influential commentators made publicly  that the war was a good idea, not because Iraq posed a real threat, but because beating up someone in the Middle East, never mind who, would show Muslims that we mean business. In other words, even alleged wise men bought into the idea of macho posturing as policy.

All this is in the past. But the state of the energy debate shows that Republicans, despite Mr. Bush’s plunge into record unpopularity and their defeat in 2006, still think that know-nothing politics works. And they may be right.

Sad to say, the current drill-and-burn campaign is getting some political traction. According to one recent poll, 69 percent of Americans now favor expanded offshore drilling  and 51 percent of them believe that removing restrictions on drilling would reduce gas prices within a year.

The headway Republicans are making on this issue won’t prevent Democrats from expanding their majority in Congress, but it might limit their gains  and could conceivably swing the presidential election, where the polls show a much closer race.

In any case, remember this the next time someone calls for an end to partisanship, for working together to solve the country’s problems. It’s not going to happen  not as long as one of America’s two great parties believes that when it comes to politics, stupidity is the best policy.
