The Greatest?

Apparently according to the Discovery Channel, Ronald Reagan is the "Greatest American." Ever. Also in the top ten were Bill Clinton, George W. Bush, Elvis, and Oprah. There other, more legitimate picks in the top ten, such as Lincoln, Dr. King, Ben Franklin, Washington, and FDR. But Bonzo, Bubba, W, Elvis, and Oprah? Come on. What about some others, Albert Einstein, Thomas Edison, Thomas Paine, Noah Webster, Theodore Roosevelt, William Faulkner, Mark Twain, Miles Davis, and this is all just off the top of my head. The BBC did their own poll where Britons could vote on the Greatest American, guess who won that one?
