incorrect.
according to the law, pedro would have been born a US and mexican citizen (assuming both parents were mexican in your example), but he would not be a natural born citizen of either country.
the VAST majority of Americans are natural born citizens and the complexities of the issue escapes them, as they can only be US citizens. but, to those of us born here with a foreign citizen parent (scottish in my case), we understand it quite well.
you see, i can hold two passports legally... US and British... as i am a US citizen and british by descent, just like 0bama. i am NOT a natural born citizen of either country and therefore would be ineligible for POTUS (liberals can breathe a sigh of relief ;)
“No person except a natural born citizen, or a citizen of the United States, at the time of the adoption of this Constitution, shall be eligible to the office of President; neither shall any person be eligible to that office who shall not have attained to the age of thirty five years, and been fourteen Years a resident within the United States.”
The first 10 words support your position.
natural born citizen and citizen, as relates to ascending the presidency, are NOT equivalent.
The Founders were not ones to waste or use unnecessary words - if their intent was no distinction, they would not have used different words to describe an equivalent position.
In 1916, the Republican Party nominated Charles Evans Hughes to be their presidential candidate and to run against Woodrow Wilson.
In California, the results were Wilson 466,289 (46.65%) and Hughes 462,516 (46.27%).
In New Hampshire, the results were Wilson 43,781 (49.12%) and Hughes 43,725 (49.06%) out of 89,000 votes cast
So a change of 3800 votes out of the 1 million cast in California and 60 votes out of the 90,000 cast in New Hampshire would have made Charles Evans Hughes the President of the United States.
Charles Evans Hughes was born in New York state in 1862 to a British subject father and an American citizen mother. His father David C. Hughes became a naturalized US citizen in 1864.
