It's not my intention...

... to make this an all Cindy Sheehan day, but there's some really great writing happening out there (all the more indication that something's working).  This from Body and Soul:

On a small scale, it [Christopher Hitchen's Slate article on Sheehan] replicates the whole Sheehan dilemma for the right. They can say anything they want. And she repudiates it before she even opens her mouth. Yes, she's clever, too -- inviting Bush to a prayer vigil; is that a stroke of genius or what? -- but that's just extra.

There's no point in arguing against the right's nonsense. As Digby recently said, "she's driving the Republicans crazy," and she's doing so because she has qualities they haven't encountered recently in public opponents -- honesty, moral authority, and questions that resonate in other Americans. That doesn't make everything she says right, but it makes her unslimable. And that's what's driving the Republicans to drink Hitchen's favorite potions. They know how to slime -- and shoot, of course. And burn run over crosses. They don't know how to disagree. Hitchens can tell you that she's not necessarily right -- which is true -- but he can't tell you why she's wrong. Slime has worked so well, they've forgotten how to do reasons and explanations. Even if there were any answers to the question why did Casey, and nearly two thousand other Americans, as well as Iraqis in at least the tens of thousands, have to die, Republicans wouldn't know how to give them.

As I mentioned below, Cindy Sheehan is just a person, and she's probably going to bungle a few things while she's doing what she believes is right.  But, even as she does, her very presence makes things more and more difficult on Bush, not because she is "right at all costs" but because her plight resonates.
