Strange…when I google “democratic leaders referring to republicans as nazis or fascists” seems to bring up quite a few results. Biden, Gore, Pritzker, Harris, quite a few more peppered about among the Democratic Party elected officials.
So...that's one? A literally-who to most lay people, but yea, it is one Democratic politician. I see your one Illinois Governer and raise you one US President:
> "These people are running a Gestapo administration. It's the only thing they have. And it's the only way they're going to win, in their opinion..."
> "Every time the radical left Democrats, Marxists, communists and fascists indict me, I consider it actually a great badge of honor.... Because I’m being indicted for you"
