McCain presented his long-form birth certificate to the Senate and tesitified, he released it to the press as well, and a non-binding resolution was passed that was even co-sponsered by Obama and Clinton.
No he did not. The WorldNutDaily article you linked to is simply wrong, and that wouldn't be the first time that website was wrong.
