I think the point is that the US wanders the world (apart from China), election-meddling and influencing and coup-ing, and then all of a sudden when it happens to us it's some kind of pearl clutching emergency and crime.
To be clear, I don't think we should be doing it to other countries, and I don't think they should be doing it to us. And I think the prospect of another Trump presidency would be so catastrophic for people the world over that it's worth resisting election interference on his behalf, even if you have no particular love for the US and its little adventures on the global stage. But certainly the US State Department getting upset that someone's influencing our democracy, even though we don't want them to, can be met with a certain amount of pure derisive laughter.
I think you broke the code yes. I think it's moderately likely that "get your hands dirty" will become a phrase we hear again in the somewhat-near future as shit gets more and more real leading up to the election.
I'm not saying that at all as a good thing, just where the GOP seems to want things to be heading.
