Michael J. Fox is making his return to the midterm elections.
After cutting some memorable campaign commercials for now-Sens. Ben CardinBen CardinDems to Clinton: Ignore Trump on past scandals Senate GOP ties Iran sanctions fight to defense bill Lawmakers push to elevate Cyber Command in Senate defense bill MORE (D-Md.) and Claire McCaskillClaire McCaskillDems to Clinton: Ignore Trump on past scandals Party chairs see reversal of fortune Why Wasserman Schultz must go MORE (D-Mo.) four years ago, Fox is back in a new spot for Sen. Arlen Specter (D-Pa.).
"Arlen Specter is moving forward," Fox says. "He's won the battles to double funding for biomedical research, to find cures and to save lives.
"He's smart, tough and always moving forward."
Fox's 2006 midterm ads for Cardin and McCaskill drew plenty of attention, especially after Rush Limbaugh accused him of exaggerating the effects of his Parkinson's disease during the ads.
Specter faces Rep. Joe Sestak (D-Pa.) in the May 18 primary. If he wins there, polls show he would also face a tough match in November, with former Rep. Pat Toomey (R-Pa.) leading.
