Woah... I live in the Metro Atlanta area and I didn't even know Collins was still in the race. Everything I've heard on radio and TV of late has been Cain or Isakson. Collins hasn't entered any of the political discussions I've had with anyone lately, either. He really needs to get his visibility up if he plans on "peaking."
Money doesn't win races in GA. Just ask Guy Millner, Roy Barnes, and Max Cleland.
I suspect Collins will do better than this article suggests.
