Michael J. Fox for inserting his halting voice into the U.S. Senate

campaign in Missouri, suggesting Fox was "acting" in a commercial where

he's shown shaking while endorsing the importance of stem cell

research.

"He is exaggerating the effects of the disease," Limbaugh told

listeners today, encouraging them to go online to watch Fox's

commercial, which first aired Oct. 21 in St. Louis during a World

Series game. "He's moving all around and shaking and it's purely an

act."

In the commercial, Fox throws his support behind Democratic Missouri

Senate candidate Claire McCaskill, who supports stem cell research,

against Republican James M. Talent. Fox also taped similar ads for

other Democratic candidates, including Benjamin L. Cardin in his Senate

race against Republican Michael S. Steele in Maryland and Wisconsin

Gov. Jim Doyle (D), who is seeking reelection.

The ads bear witness to the actor's unmistakable decline from

Parkinson's, which the actor has suffered from for a long time, and

harnesses that physical degeneration into a political message.

"What you do in Missouri matters to millions of Americans, Americans

like me," Fox said in the television spot, which will continue airing

throughout Missouri this week.

"This is the only time I've ever seen Michael J. Fox portray any of the

symptoms of the disease he has," Limbaugh said. "He can barely control

himself."

Limbaugh said Fox could "control himself enough to stay in the frame of

the picture" and to keep "his eyes right on the . . . teleprompter. But

his head and shoulders are moving all over the place."

"He is acting like his disease is deteriorating because Jim Talent

opposes research that would help him get cured," Limbaugh said, adding

that Talent only opposes "fetal stem cell research, but not adult."

"This is really shameless of Michael J. Fox," Limbaugh said. "Either he

didn't take his medication or he's acting."
