Sen. John McCain stands a good chance of winning tonight’s primary against challenger J.D. Hayworth. But that hasn’t kept him from being a victim of party-on-party attacks, so to speak. Sen. James Inhofe (R-Okla.) criticized McCain today, claiming the Arizona senator “gets elected because of one thing – earmarks.” Tulsa World reports that Inohofe, in a speech at a Tulsa Metro Chamber breakfast, attacked McCain as a closet liberal for his opposition to earmarks, which Inhofe said were no more than appropriations.
