No, that makes perfect sense - it is a self selecting group that takes the poll. In the case of Americans, it is the subset that acknowledges that the rest of the world exists. Obviously this is going to be a higher correlation with Obama voters than McCain voters. Think about it, how many McCain voters would even go to the website or care about the results?
