I think the thing that enables Facebook is also the thing that obsoletes it. If we imagine Facebook 30 years ago when mass media was still a tightly constrained venture comprised of relatively little more than television, print, and radio, then I think your point would be extremely valid. Reaching an extremely micro-targeted demographic of immense scale, in real time, and for relatively low cost? I mean yeah, Facebook would be what would decides elections. But we don't live 30 years ago. We live today. And billions of people are, in some form or another, doing exactly what you and I are doing right now. Discussing and debating ideas while influencing each other in various ways that are extremely difficult to quantify. We, in turn, are probably somewhat influenced by advertisements and the such still - but I think that people are starting to influence people more than any sort of advertising is. The one thing that has typically predicted elections success in the US is money. Whoever spends more, wins. If they spend a lot more they tend to win by wide margins. In the most recent election, one candidate spent vastly more and were relatively highly praised by the media. The person that was greatly outspent and alternatively vilified or mocked by the media in a 24/7 loop for months leading up to the election, won. For that matter even look at Bernie Sanders. A 73 year old man who refers to himself as a democratic socialist. That word polled somewhere south of cancer not that long ago. But times have changed as the internet can redefine the rules, zeitgeist, and overton window of society - in a flash. Ocasio-Cortez, a member of the Democratic Socialists of America and full of some interesting quotes, defeated a deeply entrenched representative going on to his 10th term who was still serving as the chair of the house democratic caucus. These things are not happening because any of the cliches that have been blamed. They're happening because the internet has usurped control of dialogue away from any given behemoth. And now what happens is being decided by a collective of individuals that, if nothing else, have shown themselves to be rather less than predictable.
