John McCain as the Queen of Hearts:

One might expect conservative columnist George Will to be supportive of the Republican presidential nominee, but he's none too pleased with McCain's latest pronouncements, and raises concerns about the Arizona Senator's temperament.

Channeling his inner Queen of Hearts, John McCain furiously, and apparently without even looking around at facts, said Chris Cox, chairman of the Securities and Exchange Commission, should be decapitated. This childish reflex provoked the Wall Street Journal to editorialize that "McCain untethered" — disconnected from knowledge and principle — had made a "false and deeply unfair" attack on Cox that was "unpresidential" and demonstrated that McCain "doesn't understand what's happening on Wall Street any better than Barack Obama does." . . .

In any case, McCain's smear — that Cox "betrayed the public's trust" — is a harbinger of a McCain presidency. For McCain, politics is always operatic, pitting people who agree with him against those who are "corrupt" or "betray the public's trust," two categories that seem to be exhaustive — there are no other people. McCain's Manichaean worldview drove him to his signature legislative achievement, the McCain-Feingold law's restrictions on campaigning. Today, his campaign is creatively finding interstices in laws intended to restrict campaign giving and spending. . . .

Conservatives who insist that electing McCain is crucial usually start, and increasingly end, by saying he would make excellent judicial selections. But the more one sees of his impulsive, intensely personal reactions to people and events, the less confidence one has that he would select judges by calm reflection and clear principles, having neither patience nor aptitude for either.

It is arguable that, because of his inexperience, Obama is not ready for the presidency. It is arguable that McCain, because of his boiling moralism and bottomless reservoir of certitudes, is not suited to the presidency. Unreadiness can be corrected, although perhaps at great cost, by experience. Can a dismaying temperament be fixed?

Food for thought.
