Samuel L. Jackson is the ultimate king of cool. His eminently quotable performance in 'Pulp Fiction' propelled him to the top of the 'cool' stakes, but the man possesses so much pizzazz that he even managed to make 'Snakes on a Plane' look and sound like a reasonable film. Not anybody can carry that off. He's very closely associated with the use of one curse word which can't be repeated here or within polite political discourse, so he'd have to drop that from his vocabulary, but we're sure he'd still manage to get his points across without it.
Jackson is no stranger to becoming involved in political debate either; he was an advocate for President Barack Obama, and has been an outspoken critic of conservative judge Clarence Thomas, feeling that he acts against the interests of people of color. If Jackson was in charge, he might be able to get rid of him.
