She has already admitted to multiple felonies related to mishandling classified information. Nothing happened. It is hard to imagine anything that Wikileaks could dump that would harm her at this point. There will be no criminal charges so long as Obama holds the Presidency and obviously none should Hillary win, and should she lose Trump won't waste the political capital to bring her to justice either.
Her voters already know she is a criminal, they are not voting for her in spite of the knowledge, but because of it. It demonstrates she possesses the Will to Power they consider a requirement in a leader.
