Call me a Scrooge but my read is rather that whoever wins will piss off the opposite side, who will blame social media like they did in 2016, and there is no scenario where twitter doesn't ends up the target of more regulations unless they stay away from the elections as far as they can.
This will not help with trolls and viral campaigns though.
This is a great point, but ducking out of politics is exactly the right move here to avoid that kind of charge.
Regulation will come with any functioning democracy. If an entity other than the State has too much power, Democracies will eventually dismantle or defang it, as they should.
