One of the first few American presidential candidates had to fight against the accusation by the opposing party that he was not born in the USA...his parents had been in Canada for a short time, and it was said that he had been born there, not in the USA, thus disqualifying him as a presidential candidate.

It was a silly, capricious accusation without merit or meaning, because his entire upbringing was in the USA as an American, so it wouldn't have mattered a damn anyway if he'd been born in Canada....but politics being the ruthless and cynical game that it is, they went after him for it, regardless. It didn't stop him from getting elected.

I can't remember which president it was at the moment, but I think it was James Madison.
