Instead Mrs. Clinton darkened that cloud by claiming that she was fooled by the prewar intelligence that didn’t dupe nearly half her Democratic Senate colleagues, including Bob Graham, Teddy Kennedy and Carl Levin. Even worse, she repeatedly pretends that she didn’t know President Bush would regard a bill titled “Authorization for Use of Military Force Against Iraq Resolution of 2002” as an authorization to go to war. No one believes this spin for the simple reason that no one believes Mrs. Clinton is an idiot. Her patently bogus explanations for her vote have in the end done far more damage to her credibility than the vote itself.

That she has never given a forthright speech on Iraq is what can happen when your chief campaign strategist is a pollster. Focus groups no doubt say it would be hara-kiri for her to admit such a failing. But surely many Americans would have applauded her for confessing to mistakes and saying what she learned from them. As her husband could have told her, that’s best done sooner rather than later.

It’s too late now, and so the Democratic stars are rapidly aligning for disaster. Mrs. Clinton is no longer trying to overcome Mr. Obama’s lead in the popular vote and among pledged delegates by making bold statements about Iraq or any other issue. Instead of enhancing her own case for the presidency, she’s going to tear him down. As Adam Nagourney of The New York Times delicately put it last week, she is “looking for some development to shake confidence in Mr. Obama” so that she can win over superdelegates in covert 3 a.m. phone calls. If Mr. Wright doesn’t do it, she’ll seek another weapon. Mr. Obama, who is, after all, a politician and not a deity, could well respond in kind.

For Republicans, the prospect of marathon Democratic trench warfare is an Easter miracle. Saddled with the legacy of both Iraq and a cratering economy, the G.O.P. can only rejoice at its opponents’ talent for self-destruction. The Republicans can also count on the help of a political press that, whatever its supposed tilt toward Mr. Obama, remains most benevolent toward John McCain.

This was strikingly apparent last week, when Mr. McCain’s calamitous behavior was relegated to sideshow status by many, if not most, news media. At a time of serious peril for America, the G.O.P.’s presumptive presidential nominee revealed himself to be alarmingly out of touch on both of the most pressing issues roiling the country.

Never mind that Bear Stearns was disposed of in a fire sale, the dollar was collapsing, job losses hit a five-year high, and the price of oil hit an all-time high. Mr. McCain, arriving in Iraq, went AWOL on capitalism’s meltdown, delegating his economic adviser to release an anodyne two-sentence statement of confidence in Ben Bernanke.
