You know the media is really doing good propaganda when you read some of the responses here. It's a real pity that so many are uninformed on this issue.
The main issue here is that Michael J. Fox deliberately doesn't take his medication when he is promoting political action so that his illness makes a stronger impact for sympathy. So firstly anyone who wonders whether he's acting or really sick is justified in being confused by his behavior. (So Limbaugh was reacting the way anyone would to the hoax portrayed by Fox.)
Secondly, and more importantly, the issue Fox is talking about isn't even about stem-cell research since that is already legal in Missouri. The issue is about legalizing cloning. So the voters better read the fine print because either Fox is misleading the voters or the Democrats have duped Fox into sponsoring something most find repulsive.
We're trained to have sympathy for those afflicted with disease, but when they use that disease to create credibility for their political activism, I think we can see through the ruse.
Sorry, Michael J. Fox, but I no longer have any respect for you as a person or an actor.
I used to like the guy, now I realize he's deliberately lying to people who pity him and that's wrong.
