I recorded it from TCM a few months ago, and have noticed it on a couple of times since then.

Chaplin is a clueless but lovable Jewish barber. He is injured in WW1 and has amnesia for 20 years. When he gets back home, the "Nazis" have taken over but he doesn't realize it or understand what is going on.
But since he is an exact double for the Dictator......the rest of the movie is pretty easy to predict.

Definitely worth a watch.

"Machine men with machine minds"

I don't think lower rank and file Republican voters realized that their party's basic goal is making rich men richer at all cost. Their party's bottom line is greed and they'll use any Elmer Gantry type tactics to do it.

Trump feeds these folks' need for a Messianic savior who elevates their racism above "radical lefties'" ideas.

Here Chaplin was addressing this strange need for a Messianic savior. It's exactly how dictators come into power. Scary.
