I found in canvassing when someone brings up Ayers that this argument is the most effective.
ME: "let me ask you something you in the PTA or Cub Scouts or any organization like that?"
Voter: "Yeah I got my kids in insert organization"
ME: "Well think about all the parents you know from that group. Now, do you know what every one of them was doing 40 years ago?"
Barack should have this same conversation with America tonight when McSame brings up this smear.
