NRA endorses McCain in AZ Republican primary
PHOENIX, AZ The organization announced its endorsement in a letter to McCain dated Thursday. The endorsement is a significant boost for McCain. It provides high-profile support for his conservative credentials as he tries to shake a primary challenge by former U.S. Rep. J.D. Hayworth. Hayworth has attacked McCain's record on gun rights, saying the four-term Senator has supported restrictive legislation. Hayworth touts an endorsement from Gun Owners of America, a smaller gun-rights lobbying group.
