This is stupid. No intruder is going to copy files straight to their home computer. They'll use a compromised server somewhere, and there is plenty of server to server bandwidth.
It's fine to be skeptical of course, and to be very skeptical of direct "hacking the election" (whatever that means) claims.
But there is plenty of public evidence that Russia was involved in the DNC hack. This evidence was available before the election, which makes it more credible against claims of political interference.
I've posted this before, but I think it's important people understand what public evidence is available:
(July) 2016 report into the DNC hacking, showing it was first breached by ATP-29 (The other Russian state backed hacking group), but the leaks almost certainly came from a second breach by ATP-28 later: https://www.crowdstrike.com/blog/bears-midst-intrusion-democ...
