Sen. Jim Inhofe (R-Okla.) went after his fellow GOP Sen. John McCain (Ariz.) as the latter as faced reelection Tuesday. Inhofe, rated as one of the most conservative members of the upper chamber, attacked McCain's conservative credentials and said he only gets elected because of his opposition to earmarks. The Tulsa World wrote that Inhofe "attacked" McCain as a "closet liberal," then quoted Inhofe as saying he "gets elected because of one thing -- earmarks."
