Ralph Nader

Ralph Nader is an American political activist, author, lecturer and attorney.

History
When Mr. Burns asks the Springfield Republican Party about the act of evil the Republican Party should do, Nader eagerly puts his hand up, only for Mr. Burns to tell him that he's done enough.

During the song "High to Be Loathed", Mr. Burns mentions Nader, and makes his shadow, among lots of other villains.
