(Via Mickey Kaus ) I see that Arianna Huffington thinks McCain’s campaign is falling apart because he’s supported the Iraq war. Does this strike any serious person as persuasive? Giuliani, Thompson, Romney and all the other serious candidates for the GOP nomination support the war. Meanwhile, all of the reporting I’ve seen says that McCain’s fundraising evaporated because of his immigration stance. And nearly all of the punditry — save Huffington’s — argues that McCain has no choice to become a single-issue win-in-Iraq candidate if he wants to save his campaign.
