I'm somewhere between option two and three. I think this was a pretty normal election in terms of fraud, perhaps a little more. But it was also pretty close so "normal" might have flipped it. I suspect we'll never know for sure, as the choice of cheating was (and is historically) ginning up extra ballots. Once they are mixed in with the stream there's no way to know for sure how many there were.
To zahc's point, the media advantage is every bit as strong as he says, but much like the Russian bots on FB in 2016 didn't "steal" or "hack" that election, the media didn't steal this one. If people are too lazy and stupid to recognize bias and misinformation being fed to them, I'm not sure what we can do. As long as we let stupid people think that their opinion matters and vote, we have to deal with the fact that folks are going to lie to stupid people for that vote.
