Foreign intervention with the clear aim of causing political rift doesn’t care about party lines other than the fact that they can be used to manufacture outrage and division.

If Trump was a democratic candidate or if the Dems had a different loon in play while the republicans had someone say like McCain running then the same actors would have been working in the same manner just now in favor of a different party.

These actors will exploit any vulnerability and there is no hidden intention to benefit a single party other than to further their own goals.

During the Cold War the Soviets we’re finding both communist and neo-Nazi groups in west Germany at same time because for them the goal was always to cause as much chaos as possible.

In the US during Vietnam they were funding anti-war groups on campuses again simply because they were seeking to incite as much dissent as possible.

All interests are or at least can be easily compromised it’s just a matter of circumstance and timing.
