Tuesday night must have been almost as much fun for John McCain as for Obama. The Republican brand has been badly smudged by recent foreign and domestic policies, which are the only kinds there are, so McCain's hopes rest on the still-unattached cohort called "Reagan Democrats," who still seem somewhat resistant to Obama.

McCain's problem might turn out to be the fact that Obama is the Democrats' Reagan. Obama's rhetorical cotton candy lacks Reagan's ideological nourishment, but he is Reaganesque in two important senses: People like listening to him, and his manner lulls his adversaries into underestimating his sheer toughness -- the tempered steel beneath the sleek suits.
