Pachacutec at FireDogLake about says it for me:

"Let me say this slowly. It's something I've never said before.

Bush is unfit for office. He's not my president.

Now, I've called him nuts, crazy, dangerous, said he should be censured over warrantless wiretapping, and so on. I've said he's paranoid and craven and callow and cowardly. I've said his 2000 election was undemocratic and probably illegitimate, in some fashion. Selected, then elected. And even with all that, I still mentally sustained a degree of deference to him, in some corner of my mind, as President of the United States.

I've never called for impeachment and I'm still not. I'm not raving or slamming my fingers down on my keyboard. I'm feeling very calm. I'm not trying to be funny, snarky, witty or anything else. I'm just grappling with the incredible hubris. . . words fail. "Irresponsibility" is too thin. What's the word? How does one characterize the absolute contempt this man has for human life, for the expressed will of the American people, who have completely repudiated his failed occupation of Iraq, now that he's indulging his fantasies of an escalation?"
