While I was sympathetic to McCain’s birth situation, how can the congress pass a resolution to give an “exception” to something in the constitution?
They can’t, but that was part of the theater designed to hide what was in plain sight, Obama was born a British subject and was not naturally an American.
DISCLAIMER: i hold no admiration for John S. McCain III, so hold no bias in his favour.
That said, existing US Law governing the Panama Canal Zone (McCain was born in an hospital within the Zone that was for the use of US Military and their dependents) made McCain a US Citizen at birth. By 1934 US Law governing the status of persons born within the Canal Zone, McCain was indeed a natural born citizen and therefore eligible to be US President.
The congressional declaration appears to be nothing more than window dressing. McCain was born in 1936 and would have been covered by that law before it was amended in 1937.
