Senator John McCain, locked in a bitter primary fight with former Congressman J.D. Hayworth, has scored a direct hit with a new ad ripping Hayworth apart for his appearance as a paid pitchman for a shady company selling information on how to get U.S. Government grants. Calling Hayworth a “huckster” McCain scores big, turning Hayworth’s own words back on him. Devastating ad if you are a Hayworth fan.
