I do wonder how the question was posed. I don't think many people would openly admit to supporting fascism, but if you broke the question down into certain policy choices I feel like the number would skew higher. But that could just be me.
You can do the same thing with communism. A lot of people like the policies, but shy away when you attach the word "communism" to it thanks to decades of indoctrination.
The Baron was a lot more fun in Lynch's Dune as well.
