It's actually fairly common to see these actors work both sides of the political spectrum. It's important not to over-index any specific operation, because many of these operations have a counterpart that's focused on the opposing audience.
I'll give you an example. The Internet Research Agency is the group that was so active in 2016 in the elections in the United States. They're still around, or remnants of that organization are still around, and actually, there is a very recent operation that was sort of right-facing. However, prior to that, they were doing a left-facing operation or a left wing-facing operation, so it's not uncommon to see them work from both angles.
The other thing I think is really important when it comes to this activity is that there is no favoured version of the truth. The point is often to flood the zone with narratives that are often completely contradictory to each other.
