Socialism is not concerned with the welfare of everyone. Socialism is concerned with governmental control. Mussolini and Peron and Pope Francis are all fascists and each of them was only concerned with his power base, as you suggest, and each of them was socialistic.
Fascism is socialistic; nazism is socialistic; communism is socialistic; and Jewish Bernie Sanders is socialistic and honeymooned in the USSR and interned at a Stalinist kibbutz, a socialistic farm, in Israel, as you know.
I think that you want another word to describe Trump. How about ex-Democrat?
Sorry, but you are only showing your ignorance, which you insist on maintaining. No need to talk more. So, just keep spitting into the wind. You do know what happens when you spit into the wind, don't you?
