Protest the Hero. They certainly have a tendency toward being hamfisted, but I guess you kind of need to be. I guess the same could also be said of Dead Kennedys, though they were a bit more elegant (according to the Lore as far as I remember, the first album was written by Biafra and another guy who was more interested in just trying to be "shocking," making the songs really inconsistent in quality and subject matter and values, but then he left and it got better)

I'm also surprised at the relative lack of leftist rappers mentioned here.
