The "realpolitik" is in fact, and almost by definition, not online.

I think a ton of people didn't get the memo during the first Trump term, and are still baffled by it during his second one.

Republicans have never used the media like the Democrats. Conservative values change very slowly and are disseminated through institutions like the military, religion, etc. Trump has taken it to the next level by only ever using the internet to troll the chronically online and anyone else out of the loop. That's radio discipline.
