I think this is a ploy to help explain the “tightening of the polls” in order to create enough believability in the polls to substantiate their getting away with stealing the election.
Nah, they didn't need to do this to help with that. They were already blaming wikileaks for the exact same thing. But you have a point that this is being reported big time by outlets that normally would just suppress it. Somebody really wanted to make this an issue for the Clinton campaign.
