Why aren't you reading Ta-Nehisi Coates? Seriously, why aren't you?
He might be the best political/cultural commentator of my generation. I don't think he does much (or any) TV. (Not watching very much of that sort of TV myself, I cannot be completely sure.) You will occasionally hear him on NPR's On the Media (which is itself excellent.) But, mostly, you will find Mr. Coates blogging at The Atlantic.
Check out this take-down of Juan Williams, which actually reads much better as a broad critique of the intellectual laziness that characterizes modern punditry of all political persuasions.
