Hillary Clinton may not realize it yet, but she's just endured one of the worst weeks of her campaign.

 First, Barack Obama weathered the Rev. Jeremiah Wright affair without serious damage to his nomination prospects. Obama still holds a tiny lead among Democrats nationally in the Gallup tracking poll, just as he did before this whole affair blew up.

Second, Obama's lawyers successfully prevented re-votes in Florida and Michigan. That means it would be virtually impossible for Clinton to take a lead in either elected delegates or total primary votes.

Third, as Noam Scheiber of The New Republic has reported, most superdelegates have accepted Nancy Pelosi's judgment that the winner of the elected delegates should get the nomination. Instead of lining up behind Clinton, they're drifting away. Her lead among them has shrunk by about 60 in the past month, according to Avi Zenilman of Politico.com.

In short, Hillary Clinton's presidential prospects continue to dim. The door is closing. Night is coming. The end, however, is not near.

Last week, an important Clinton adviser told Jim VandeHei and Mike Allen (also of Politico) that Clinton had no more than a 10 percent chance of getting the nomination. Now, she's probably down to a 5 percent chance.

Five percent.

Let's take a look at what she's going to put her party through for the sake of that 5 percent chance: The Democratic Party is probably going to have to endure another three months of daily sniping. For another three months, we'll have the Carvilles likening the Obamaites to Judas and former generals accusing Clintonites of McCarthyism. For three months, we'll have the daily round of resume padding and sulfurous conference calls. We'll have campaign aides blurting "blue dress" and only-because-he's-black references as they let slip their private contempt.

 For three more months (maybe more!) the campaign will proceed along in its Verdun-like pattern. There will be a steady rifle fire of character assassination from the underlings, interrupted by the occasional firestorm of artillery when the contest touches upon race, gender or patriotism. The policy debates between the two have been long exhausted, so the only way to get the public really engaged is by poking some raw national wound.

For the sake of that 5 percent, this will be the sourest spring. About a fifth of Clinton and Obama supporters now say they wouldn't vote for the other candidate in the general election. Meanwhile, on the other side, voters get an unobstructed view of the Republican nominee. John McCain's approval ratings have soared 11 points. He is now viewed positively by 67 percent of Americans. A month ago, McCain was losing to Obama among independents by double digits in a general election matchup. Now McCain has a lead among this group.

For three more months, Clinton is likely to hurt Obama even more against McCain, without hurting him against herself. And all this is happening so she can preserve that 5 percent chance.

When you step back and think about it, she is amazing. She possesses the audacity of hopelessness.

Why does she go on like this? Does Clinton privately believe that Obama is so incompetent that only she can deliver the policies they both support? Is she simply selfish, and willing to put her party through agony for the sake of her slender chance? Are leading Democrats so narcissistic that they would create bitter stagnation even if they were granted one-party rule?

The better answer is that Clinton's long rear-guard action is the logical extension of her relentlessly political life.

For nearly 20 years, she has been encased in the apparatus of political celebrity. Look at her schedule as first lady and ever since. Think of the thousands of staged events, the tens of thousands of times she has pretended to be delighted to see someone she doesn't know, the hundreds of thousands of times she has recited empty cliches and exhortatory banalities, the millions of photos she has posed for in which she is supposed to appear empathetic or tough, the billions of politically opportune half-truths that have bounced around her head.

No wonder the Clinton campaign feels impersonal. It's like a machine for the production of politics. It plows ahead from event to event following its own iron logic. The only question is whether Clinton herself can step outside the apparatus long enough to turn it off and withdraw voluntarily or whether she will force the rest of her party to intervene and jam the gears.

If she does the former, she would surprise everybody with a display of self-sacrifice. Her campaign would cruise along at a lower register until North Carolina, then use that as an occasion to withdraw. If she does not, she would soldier on doggedly, taking down as many allies as necessary….
