GOP: - Bob Novak says McCain is 50/50 shot to run in '08. He will be 72. I think I'll knock him down slightly in the odds, to 5:1 (tied with Rudy). - Sen. Specter backs the "Arnold Amendment", but that doesn't make it any more likely to happen. - And I'm moving Bill Frist up from 5:1 to 4:1, making him my new leader for the GOP nomination (slightly over Chuck Hagel, who really hasn't been anywhere lately and might fall if he doesn't start making some noise).
