After Gary Hart was photographed with a model (no, not his wife) in 1988 on a boat dubbed Monkey Business, Massachusetts Governor Michael Dukakis became the Democrat's choice to run for President against George Bush.
At a General Dynamics plant in Michigan, the Duke wanted to show he was no softie on defence, so took a spin in a tank. Compared with the dashing WWII pilot Bush, the little Dukakis came off a clown, and the photo op blew up in his face.
