Progressive used to mean very liberal around the turn of the centenary and yes Republicans used the label. After WW2 it's the label that communists hid under to this very day. Trump's a 100% capitalist. If you can't tell the difference between a communist like Hillery or Obama and a capitalist like Trump then you might need to see your doctor about that.
I'm not the one calling Trump a "progressive."
I know what the various terms mean, quite well. I've listened to more than my fair share of communist and progressive propaganda. Once you account for the cultural differences between the USSR and the US, the difference between the two becomes a matter of terminology, not substance.
