Obviously she is exaggerating with the "unknown" part but she's right, he wouldn't be nearly as popular.
I'm not sure I agree with that statement. Sure, in surveys Canada is bigger on the whole 'MMA' scene but our population is literally 10% that of the USA. By this logic, one can emphatically conclude that GSP must have quite the American following, as dictated by his constantly sky high PPV buys. So it stands to reason through this thought process that he has many American fans keeping his Canadian fans company. I would be very surprised to find a Yankee who is a GSP fan simply because he is good looking and Canadian.
