This is good:

In the past, the fight has been worth it. Bush almost always gets his way and usually enhances his standing in the process.

But it’s one thing to push a program against the will of the system. It’s another thing to push a person. A person bleeds. At some point, Bush’s refusal to scuttle Miers’ nomination may turn into an act of cruelty…

We may not be at that moment yet, but Washington is experiencing something like tissue rejection over Miers.

I love that last metaphor.
