Russia hacks everything all the time.
That's not news.
What is news, is the fact that the commies don't like the DNC's hesitation (in their minds) to go full commie. As a result they are showing them how much power they truly hold over the party in an effort to get a real commie nominated in 2020.
But Hillary doesn't want you to know that. So they go to the old standby. Putin.
