Really?? There are actual communists and anarchists winning elections in the US west coast these days (e.g. Sawant, a Marxist and Chesa Boudin, an anarchist who worked for Hugo Chavez).
The SF politicians who continue to higher office tend to be mainstream Democrats: Kamala Harris, Dianne Feinstein, Gavin Newsom, Scott Wiener, David Chiu, etc.
Does that make the Republican party nazi? Absolutely not and you should not project your feelings on an entire political branch.
