PHOENIX (AP) — Sen. John McCain's Republican primary challenger has released a new ad using McCain's own voice admitting to lying in the past. Former congressman J.D. Hayworth's campaign released the commercial Thursday. It uses McCain's voice from the recording of his 2002 book, in which McCain recalls publicly supporting South Carolina's right to fly the Confederate flag, even though he personally opposed it. McCain says on the recording: " ... it could come down to lying or losing. I chose lying." The ad suggests McCain is again lying about his record on illegal immigration.
