The Horseshoe Theory says those on the political fringes have much more in common with each other than with centrists. They tend to be authoritarian, contemptuous of democracy, convinced of their inerrancy – and can and do flip to the other side, a tendency which is easily exploited and manipulated.
During the 2016 presidential campaign I watched on social media as some Bernie supporters ended up supporting Trump, which is jaw-dropping political illiteracy.
We’re seeing it now as some lefties suddenly think Trump getting played by DPRK and signing a meaningless agreement with no enforcement while ignoring long-time allies is somehow a good thing.
