Frum again:

George W. Bush had very slight executive experience before becoming president. His views were not well known. He won the nomination exactly in the same way that Palin has won the hearts of so many conservatives: by sending cultural cues to convince them that he was one of them, understood them, sympathized with them. So that made everything else irrelevant in 2000 - as it seems again to be doing in 2008. I do credit George W. Bush with great feats of leadership. In particular, I think his refusal to quit Iraq in 2005-2006 when everybody was urging him to, his insistence on fighting through to success, will be seen as a triumph of strength and conviction that saved the US from potential disaster. But he lacked other important aspects of leadership which is how we got into the mess from which he needed to rescue the country and himself...

I am not denying that Sarah Palin may have great skills. She may well. I am insisting that neither you, nor I, nor John McCain has any valid reason to believe that she does. This is not an argument about the attributes she lacks. It's an argument about the information we lack. I am pleading with my fellow conservatives: Please demand more and better knowledge before you commit yourselves to a political leader. That's all.

This decision is not worthy of a great power. Whatever skills Palin may turn out to have, however fabulous a person she may turn out to be, even if she becomes the Eva Peron of Christianism, McCain

had no idea when he picked her.

He winged this. That's the critical, unavoidable, devastating point.

John McCain has demonstrated with this insane decision that he is unfit to be president of the United States. This was an act of near-criminal negligence. If he can behave this recklessly and impulsively with this decision, the idea of allowing him to become president of the United States is only a smidgen less terrifying than thinking of Palin in that position.

Whatever few doubts I may once have still had about this election, they are resolved now.

Obama has to win. The alternative is unthinkable.
