That's also why in 2016, a year's worth of "Trump is terrible" articles only helped him - because the actual received message was "we, the people you despise, really would hate if Trump was elected". It's a sign of authenticity. Trump couldn't betray them, because he very evidently had nowhere else to go.
Aka polarisation. When Trump first won I conceptualised it as him arbitraging humanity/democracy's lack of preparedness for social media and the internet upending established flows of information.
The solution at its heart is to reduce conflict and bridge the gap. I have enjoyed Zachary Elwoods most recent podcast episode showing how Trump is misquoted by traditional media outlets which has the negative effect of furthering the perception of bias.
