I've started limiting my reading to the first couple of comments and their responses. Anything more sends my blood pressure through the roof, something I can't really afford at my age. 
Plus, I find that comments can get repetitive pretty quickly on some of those threads.
I have observed that the overall number of trolls appears to be decreasing. This seems more evident on the threads dealing with hard news stories directly focused on issues striking at Trump supporters/critics alike (such as the rescinding of the FHA mortgage insurance rate cut) as well as stories that begin to look more like the descent of outright fascism (such as the various actions to control the message in favor of the administration). No numbers to support this, just an observation of what appears to be happening. 
I've toyed with the idea of attempting some sort of analysis of troll response to political topics on FB, but my time for that kind of thing is currently focused on another aspect of the election.
