That seems high, but I once read a metasurvey -- that is a survey of surveys -- that shows that universally, across all Western democracies, around 36% will always vote for the strongman, the one who tells them "you're the special one, the entitled one, and I'll be working for you". So they start off with an advantage, they only need to persuade another 15%, not the whole 51% everyone else does.
