A good explanation of what Russia is trying to accomplish with the e-mail leaks is to release a lot of legitimate e-mails, let the press get comfortable with them and cite them as real, then towards the end start releasing doctored e-mails, which the press will continue to report as legitimate, and the Clinton campaign will now have a much harder time debunking.  So far I haven't seen much in the e-mails that is really a scandal - basically they are Podesta's words, not Clinton's, and they reflect him bouncing campaign ideas off of people - not necessarily reflecting Clinton herself's views or policies.  When the real scandalous stuff starts dropping (if ever), I suspect it will be Russia's doctored e-mails, released too late for the Clinton campaign to rebut.
