Richard, we had "two queens" back with Richard the Lionheart, according to some historians... Although the Greeks and Romans were well ahead of us on that score.

FWIW, I'd be more interested to find whether the US would elect someone who was non-Christian. By that I don't necessarily mean Muslim, Sikh or whatever, but more simply just someone who doesn't go to church. As an outsider, this seems to me to be a much bigger political division.
