What a load of disinformation.
First McCain was born on US controlled territory and subject to US jurisdiction. Cruz was not. 2nd, section G is on citizenship aka naturalizing, not about changing birth status. All it does is makes him a citizen.
By the Hypocritical former birthers for Cruz arguments Prince Hamzah Bin Al Hussein of the Arab Royal Family can become our President since Cruz and him have the same birth situation.
Think about this for a second. Your arguments allow for the ISIS raised child of a raped American missionary in Syria to be our president.
The reason we have such a law was to prevent Britain from retaking America by using the children of loyalists who had one American parent but no loyalty to America to become President and sabotage us, Like Obama has been doing.
It's a good thing England was far away, clear across the Atlantic Ocean....OH WAIT!
What about Canada!
