On a serious note, though, here's what official Washington is worried about:

It is very unlikely the Russians could sway the actual vote count, because our election infrastructure is decentralized and voting machines are not accessible from the Internet. But they can sow disruption and instability up to, and on, Election Day, more than a dozen senior U.S. officials tell TIME, undermining faith in the result and in democracy itself.

Trump is doing everything in his power now to convince his supporters that the election is going to be rigged, and it's working with about half of them. All those crazy conspiracy theories he suggests in his rallies—from being given a faulty mic at the debate to Google suppressing bad Hillary news—contribute to the narrative that he's being conspired against. He's laying extensive groundwork to make the claim, when he loses, that Hillary fixed it, that the election will be illegitimate.

Which is just what the intelligence community thinks Russia might be up to—eroding confidence in the election, in our democratic process, in a Clinton presidency. Coincidentally, all the things that Trump is trying to achieve. Does it mean Trump is in Putin's pocket? Of course not, which is not to say he wouldn't be happy to be there. Whether or not Russia has anything to do with it, Trump has spent the whole of Barack Obama's presidency devoted to his birther cause and making Obama illegitimate. He's intent on doing the same to Hillary Clinton.
