Except that Clinton's behavior continued and he smeared anyone who tried to expose it.
Of course, you do have a point, if folks already like Arnold, they are less likely to be swayed by something like this. I assume that you are not a fan of Arnold's candidacy and/or you have another person you'd rather see in office. You probably won't be swayed either.

If I had to guess, it's that Coleman takes "upskirt" photos of women. And that he has an iron clad defense......
