Have you no sense of decency, ma'am, at long last?

So does the Daily Kos accuse Cindy Sheehan, the military mom with absolute moral authority to criticize George Bush and the U.S. war effort in Iraq by virtue of her son's death in combat, for crossing the line that puts her beyond the pale by planning to oust Nancy Pelosi from her congressional seat. The Kos has revoked Sheehan's posting privileges at Daily Kos for hers betrayal of the one principle that is held sacred by all leftists: challenging an incumbent Democrat.

Now that Kos has proclaimed an official anathema on Sheehan, the left's rank and file are free to trash her memory, and the Guardian's Niall Stanage does just that in today's edition:

Even the American left's netroots are getting tired of Cindy Sheehan. It's a shame it took them so long.

Sheehan, the epic narcissist who became the face of the anti-war movement, has been banned from posting any further entries on Daily Kos, arguably the most influential of all liberal blogs in the US.

The Kossacks have pulled the plug on Sheehan because of her threat to challenge the speaker of the House of Representatives, Democrat Nancy Pelosi, for her congressional seat.

Sheehan has said she will decide on July 23 whether to go ahead with her attempt to oust Pelosi - who is, incidentally, about as liberal as congressional Democrats get - from her San Francisco district. "Democrats and Americans feel betrayed by the Democratic leadership," Sheehan recently proclaimed with her customary certitude.

As most people know, Sheehan came to prominence in summer 2005 when she set up camp outside President Bush's Texas ranch. She demanded to meet the president to discuss the death of her son, army specialist Casey Sheehan. He was killed in Iraq in April 2004.

It would be inhumane not to feel sympathy for Cindy Sheehan's loss. But it would also be softheaded to ignore the numerous inconsistencies, self-aggrandisements and missteps that have characterized her behaviour.

Sheehan's initial demands to meet Bush, and her escalating criticisms of him, had a peculiar genesis. Sheehan in fact had already met Bush before she rolled up to the ranch. Interviewed by a local newspaper after the early encounter, she restrained herself to rather mild criticisms of the war's conduct. Of Bush himself, she said he was "sincere" about wanting freedom for the Iraqi people. "I know he's sorry and feels some pain for our loss," she added.

That seems a rather circumspect judgment on a man she would later denounce as "the Fuhrer" and the biggest terrorist in the world.

Less than two months ago, Sheehan announced her "resignation" from the anti-war movement. "I am finished working in, or outside of this system," she wrote. She told the Associated Press: "When we come back, it definitely won't be with the peace movement with marches, with rallies and with protests."

All that remains is the show trial, and editing her out of all photos of her with prominent leftists.
