He must mean he’s not a socialist, he’s a communist...
Obama is not a communist as he has no interest in the government owning the means of production. He is a fascist who believes the government should control private owners and tell them how to run the means of production. A fascist is more insidious than a communist becuase they want all of the control but none of the responsibility to produce.
I like the way PJ O’Rourke put it: Liberalism is Communism sold by the drink.
