If all liberals are socialists, why is there only one Bernie. Even he's really a social democrat, but in the Overton Window of American politics, he calls himself a socialist. As for the Squad, well, IMHO they are not socialists, but there's only four of them.
I can tell you the Freedumb Caucus of Tea Partiers and QPublicans is much larger (10x as many members), and yes I do think it is fair to call Trump and many MAGA followers "fascist lite"..... just as I would some of the people they adore, like the new Italian PM Meloni, or Marine Le Pen, Erdogan, or Viktor Orban. which tells you about the U.S.' Overton Window.
In any case, socialism is still not communism, the French Socialist Party is not trying to turn France into a totalitarian dictatorship of the proletariat.
I think the U.S. Communist Party still meets in Gus Hall's garage, sitting around staring adoringly at pictures of Josef Stalin and Mao.
