on The Great Divide

So what does the conversion of Mr. McCain into an avowed believer in voodoo economics — and the comparable conversions of Mitt Romney and Rudy Giuliani — tell us? That bitter partisanship and political polarization aren’t going away anytime soon.

There’s a fantasy, widely held inside the Beltway, that men and women of good will from both parties can be brought together to hammer out bipartisan solutions to the nation’s problems.

If such a thing were possible, Mr. McCain, Mr. Romney and Mr. Giuliani — a self-proclaimed maverick, the former governor of a liberal state and the former mayor of an equally liberal city — would seem like the kind of men Democrats could deal with. (O.K., maybe not Mr. Giuliani.) In fact, however, it’s not possible, not given the nature of today’s Republican Party, which has turned men like Mr. McCain and Mr. Romney into hard-line ideologues. On economics, and on much else, there is no common ground between the parties.
