These are fun to discuss. I do think it’s more interesting to discuss broader trends than individual politicians. Even if Trump loses, for example, there’s likely to continue to be serious populist, “anti multicultural” (to put it lightly) political forces to contend with across the globe in 2020s.
Moreover elites will continue to assume that demographics will eventually solve this problem, and continue to be disappointed when this doesn’t come true. All you have to do is look at slowing immigration in the US and how previous Democratic constituencies continue to switch towards the populist Republican messaging.
