This Michael J. Fox ad is just another version of what Ann Coulter referred to in her book as Democrats' tactic of using people who they think are immune from criticism to do hatchet jobs on their opponents. If it's not Max Cleland, it's Cindy Sheehan or the Jersey girls, or now Michael J. Fox. John Edwards even appropriated Christopher Reeves.
There are two sides to the stem cell debate. Using Michael J. Fox was a powerful tactic. If he was exaggerating his symptoms, it was despicable. He certainly didn't look that way the last time I saw him on TV, which I think makes it fair game to question.
The basic concept here is if you don't want to be attacked, don't make attack ads.
