I mean, Hitler never got a majority with the NSDAP. I think he actually got like 30% of the vote or something, and became the biggest party, but far away from a majority.
The issue was that the centre-right parties were scared of the left-winged / communist parties, so they decided to cooperate with Hitler.
Basically, it’s usually centre-right politicians that give rise to radical right politicians, and the radical right politicians don’t need a majority, to get into power.



I mean, look at it this way: 2/3 of Europeans don’t support populists.
Furthermore, since most European countries do not have a two-party system, this means that European countries can govern with a 2/3 sane majority, and try to ignore the populists’ 1/3 in the Parliament.
