The Lewinsky scandal gave Hillary huge approval ratings. The American people felt bad for her and she gained a huge amount of sympathy.
Dragging that out again, especially when so many voters don't care or don't remember it, would just hurt Trump.
Not to mention the whole matter is just irrelevant regarding the issues of present day.
Of course, but with Trump, it is already a given that this election will be about everything
other than the issues. Trump doesn't win by being the best man for the job, he wins by destroying the image of the other candidates.
In this regard, I think Clinton may actually have a little advantage - Her image is already crap and she is pretty well defined at this point, so it's hard to go much lower.
