Celebs aren't always helpful.
Actor and Parkinson's sufferer Michael J. Fox stumped forpro-stem-cell-research initiatives and candidates--and endured RushLimbaugh's taunts. To what end? Missouri voters backed a ballot measurefor research, but postelection polls showed that Fox's ads hurt hiscandidate Claire McCaskill more than they helped.

It's a little annoying that Time doesn't cite what polls it's referring to. I found this chart on Pollster -- a compilation of several polls. It's hard to tell for sure but it does look like McCaskill may have lost some support around Oct. 23, the day the ad started running, especially as indicated by SurveyUSA.
