"It detracts me from supporting Hillary, by far," undecided South Carolina voter Dave Slimmer said of Bill Clinton's enormous presence in the campaign. "I think he is having too much of an influence in it, too much say, too many things meddling."
Other voters agree. Martha Fogie, who is undecided, but leaning towards Illinois Sen. Barack Obama, thinks Bill Clinton needs to tone it down.
"It's a good thing to support your wife, but I think he has gone overboard," Fogie said. "I think they are using him as the bad cop, good cop scenario, and I am very disappointed."
Hillary Clinton defended her husband in a debate, Monday night, and said that he was not overshadowing her.
"I think that he is very much advocating on my behalf," Clinton said. "And I appreciate that. He is a tremendous asset. And he feels very strongly about this country, and what's at stake, and what our future should be." However, she added that "this campaign is not about our spouses. It is about us."
Bill Clinton seemed to acknowledge that he might have to tone it down, when one woman at an event said she was sick of seeing all of the "bickering and baiting" between Hillary and Obama.
"That is pretty good advice," he said. "It is interesting, that is probably good advice for me, too. This is a lot harder for me than campaigning for myself ever was. When I was running, I didn't give a rip what anyone was saying about me. But when you love someone, it is harder."
