George Will writes on McCain's temperament, seen through the incident of McCain's opinion that that SEC chairman Cox should be fired, found in the Washington Post, Sept. 22, 2008, "McCain Loses His Head". Two excerpts:

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.

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?

The Supreme Court is on the line here. I know what I have to do.
