It bothers me a little about the Russians "supporting" Trump AND Bernie. It sounds a little too "on the nose." As if the Russians expected to be caught one day and wanted to make sure a certain political viewpoint would be tainted.
You got downvoted, but yeah - I do think that's part of the plan. To sow confusion and distrust. An article on NPR talked about how russian bots were playing both sides of the gun control question in the last few days. If the goal is just to destabilize US politics, then consistency is no virtue.
