Third-party write-in candidate?
During the height of Beatlemania in 1964, there was a borderline serious effort to draft Ringo Starr for president. There were buttons, t-shirts, rallies and even a novelty song recorded in two hit versions: One by Australian entertainer Rolf Harris (famous for "Tie Me Kangaroo Down, Sport"), the other by a studio group called the Young World Singers.
The campaign even earned a mention in Theodore H. White's best-selling book, "The Making of the President 1964."
I can think of worse choices.
