For one thing, America may be a republic of amnesiacs, but deep in some seldom-used brain lobe, it does recall that its two political parties have differed on questions of regulation and stimulating the economy, a comparison that does not now work in Republicans' favor. For another, presidential debates aren't distractions from the business of the nation. However confining their formats may at times be, they are central to the business of democracy, and suspending that business so that a lowest-common denominator consensus can be reached in Washington -- or so that McCain can complain that Obama is an obstructionist if he doesn't go along with McCain's proposals -- is an affront to American voters.

McCain's ploy was transparent. To counter the public's preference for Obama's economics over his own, he would get both of them in a room and emerge proclaiming that they had reached agreement, that they had no differences. In fact, they have very real differences. McCain wants to retain tax cuts for the wealthiest Americans; Obama wants to create tax cuts for all but the wealthiest 10 percent of Americans. Obama favors policies -- through investments in infrastructure and education and through legislation enabling Americans to join unions without fear of being fired -- to build the base of the economy, while McCain's record is one of opposition to such policies. Obama favors trade agreements only when they raise labor and environmental standards with our trading partners and protect them here at home; McCain has supported every trade pact that has weakened such standards and has never said one word about protecting our standards or raising them abroad.

Comparisons such as these are odious, however, to McCain's prospects.

He cannot win on the strength of his positions. He can only win on the strength of his character. Problem is, McCain's character, as we have seen in his selection of Sarah Palin as his running mate, is heavy on decisiveness and weak on judgment. In this, despite his campaign's protestations, a McCain presidency would be very much an extension of George W. Bush's. The president helped McCain out last night by inviting both candidates to Washington today to put their imprimatur on a deal that seemed near completion. At the risk of making McCain's gesture look less heroic, he also made it look less self-absorbed.

But self is McCain's selling point. He is either the man on horseback riding to the rescue, or he is nothing -- or, more precisely, the loser come November. Obama, Lord knows, has his flaws, but he does not seem to believe that the nation's crises are primarily about him.
