Futile even if successful. It’s just for show, or perhaps it’s an exercise in stupidity. Let’s assume that they’re successful in removing Trump. Mike Pence becomes President. For VP he nominates Pat Buchanan, or Sarah Palin, or Tony Perkins, or Louie Gohmert. Are the Democrat rabble-rousers any better off in advancing their agenda? No. They may have more approval from the anarchist wing of the Democrat Party, but that’s about it.
Though the rest of your post is spot on, let's stop right there.
Removing Trump will be telling us conservative peasants that we can vote all we want - but if our guy wins, the Swamp will just remove him.
So, basically, they would be telling us that the Swamp has to be removed.
President Trump is draining the Swamp, but it's only tentative fiscal pain for them right now.
If they want REAL pain, they can tell us that our votes don't count.
Then, "Muh Russians" in their snappy copper & brass uniforms will do the voting...
