Michael J. Fox helped create a political ad for Missouri Senate candidate Claire McCaskill, in which he calls on Missouri voters to consider McCaskill's support for stem cell research. Needless to say, her opponent is against stem cell research.  Now, bring Rush Limbaugh into the picture and let him iron out the details for us all.

 

Limbaugh actually claims that Fox was acting in the ad!  The man has no shame.  Take a look at the ad for yourself, and realize that involuntary movements are a part of Parkinsons disease.

Rush's comments:

 He is moving around and shaking, and it is purely an act

Rush later apologized, as he realized there was no true way to bring politics into this situation.
