What I find most surprising is that all that political spam on Facebook drives engagement so much. At this point I barely get on it and never interact with my timeline, because half of it is shitty ads and the rest repetitive politics, and my mental model of people has most of us being turned off by it. Apparently not, though I do wonder if Facebook is somehow oversampling on a particular kind of engagement.
Don't be surprised that your (and likeminded people's) experience may not be representative of the world or even the country's at large. Poll after poll shows that 40% of the USA still supports Donald Trump.
Remember the famous (mis)quote "How could Nixon have won? Nobody I know voted for him"
