Not really. According to Donofrio McCain isn't eligible to be president either so he didn't lose anything.
John McCain was born on August 29, 1936, at Coco Solo Naval Air Station in the Panama Canal Zone, born to naval officer John S. McCain Jr. and his wife, Roberta. At the time of his birth, the McCain family was stationed in the Panama Canal Zone, under American control. This makes McCain a natural born citizen.
