Regardless of motivation, electoral choices have consequences that voters collectively own.
Again, it’s not like we haven’t seen this before in other countries that have voted in populists. It’s always the same cycle: Widespread dissatisfaction promotes populists who correctly identify legitimate problems but offer implausibly simple solutions to solve them. Voters choose the populists out of anger & frustration, only to find that they can’t solve the problems but create the kind of institutional damage that reduces the ability of any successors to solve those problems.
Trump is a populist and we’re already seeing that institutional damage merely 100 days in. There’s no indication that the outcome will be any better than all the other historical parallels.
