Thanks for the short and to the point analysis

Those are some quick & dirty POIs.
I think its also a significant factor that a lot of leftys were of Jewish heritage. Hitlers' maniacal obsession with all things Jewish or "Zionist" I think caused a re-think of his place on the political spectrum. They didn't want to be at the same end of the scale as him and his followers.
Just another quick thought.
