Demagogue

The phrase "a jury of one's peers" is misunderstood. For one thing, it's not in the Constitution. For another, it refers historically to the right of a British peer (i.e., nobleman) to be tried before the House of Lords, rather than by a jury of commoners.

Be that as it may, and conceding that I've never been mistaken for the Duke of Westminster, I wouldn't want to entrust my fate to the Jury Pool from Hell.
