This was 2001 when Donald Trump was a registered Democrat
Former Democratic New York governor Mario Cuomo evoked the image of "Republican storm-troopers." Another New York Democrat, Congressman Major Owens, went further: "These are the people," he thundered, "who are practicing genocide with a smile: they're worse than Hitler." The ideas that the Gingrich Republicans stood for—limited government, welfare reform, tax cuts, deregulation—don't seem to have all that much to do with Nazism and the Holocaust. But in the political rhetoric of today's liberals, fine distinctions often get lost.
Just reminder, being civil to America's left doesn't mean you'll get civility back for you rookies out there.
