SpaceCadetGentlemanJonWith the current poll situation if Wikileaks has anything truly explosive to publish then there's a good chance that it will swing the election in Trump's favour. However I think if they had the ammo they'd have used it already. It doesn't make sense to indulge in such brinkmanship with an election date, if manipulating the election is their agenda they'd want to allow time for the Trump campaign to properly exploit the material and disseminate it's most lurid interpretations.
Time is running short for something like that to come together coherently. Although there'd be an initial feeding frenzy it wouldn't support the kind of sustained development of an attacking narrative the Trump campaign would want. If they do have the emails and their contents were disappointingly benign then a late release might make sense - the longer Wikileaks waits the less likely they are to contain anything new or interesting, or of course the less likely they have them at all.
That could all be true but the most important factor is that nobody knows what agenda WikiLeaks is working in this case.
I think the biggest impact possible would be for Clinton to get elected amid all this building controversy then have a sitting president get charged with a crime and possibly put on trial and impeached.
The big question is "why would WikiLeaks want to help Donald Trump win?". They don't seem to have any dirt on him, at least no dirt on the level of Clinton so who knows.
People questioned wikileaks on why they have no dirt on Trump and their answer was that there is nothing they can leak that is more controversial than what Donald Trump says on a daily basis.
