I suspect that conservative and Republican communication will be totally absent for the last week before the election and it will be too short a time for anything to be done about it. Trump will disappear totally from FB etc and the networks except for Fox and it will be limited to the commentators without which Fox will rapidly cease to exist. Unlike CNN, Fox still has to make a profit.
And during the chaos after the election any mention of the Democrat cheating will be classified as a conspiracy theory and deleted.
Good old canvassing should help to mitigate the SM barriers.

And we know whats keeping CNN afloat.
