Dual citizens are eligible to be president and in fact we have had several. James Madison was a dual citizen since he was made a full voting citizen of France during the French Revolution, and Woodrow Wilson was born a dual citizen since his mother never gave up her British subject status when she became a dual citizen herself on marrying Wilson's father.And EVERY CHILD born on US soil except for the children of foreign diplomats and members of an invading army is a Natural Born US Citizen.“What is a natural born citizen? Clearly, someone born within the United States or one of its territories is a natural born citizen.” (Senate Judiciary Committee hearing on OCTOBER 5, 2004)--Senator Orrin G. Hatch (R-UT).“Under the longstanding English common-law principle of jus soli, persons born within the territory of the sovereign (other than children of enemy aliens or foreign diplomats) are citizens from birth. Thus, those persons born within the United States are "natural born citizens" and eligible to be President. Much less certain, however, is whether children born abroad of United States citizens are "natural born citizens" eligible to serve as President ..."---- Edwin Meese, et al, THE HERITAGE GUIDE TO THE CONSTITUTION (2005) [Edwin Meese was Ronald Reagan’s attorney general, and the Heritage Foundation is a well-known Conservative organization.]"Some birthers imagine that there is a difference between being a “citizen by birth” or a “native citizen” on the one hand and a “natural born” citizen on the other. “Eccentric” is too kind a word for this notion, which is either daft or dishonest. All three terms are identical in meaning."---The Wall Street Journal (http://online.wsj.com/article/SB10001424052970204619004574322281597739634.html?KEYWORDS=obama+%22natural+born+citizen%22+minor+happersett)"Every child born in the United States is a natural-born United States citizen except for the children of diplomats.”---Senator Lindsay Graham (December 11, 2008 letter to constituents)More reading on the subject:http://www.fredthompsonsamerica.com/2012/07/31/is-rubio-eligible/http://www.economist.com/blogs/democracyinamerica/2012/02/birtherism-2012http://www.obamabirthbook.com/http:/www.obamabirthbook.com/2012/04/vattel-and-natural-born-citizen/http://en.wikipedia.org/wiki/Natural-born-citizen_clause_of_the_U.S._Constitutionhttp://tesibria.typepad.com/whats_your_evidence/scotus-natural-born-citizen-a-compendium.html
To be a Natural Born Citizen you must be born within the United States and both of your parents must be Citizens of the United States. There is a clear distinction between a Citizen and a Natural Born Citizen and Article II increased the qualifications for President for good reasons.
Re: "both parents must be.."Who told you that?Re: "There is a clear distinction between a citizen and a Natural Born Citizen."Yes there is a distinction. It is that the category CITIZEN includes naturalized citizens. In contrast, the category NATURAL BORN CITIZEN excludes naturalized citizens. That is the only difference.ALL citizens born on the soil of the USA are NBCs.BTW, the term used to be commonly understood. In WWI, when men registered for the draft, they were asked whether or not they were citizens and then if they answered yes, whether they were natural born or naturalized.Get it? If you are a citizen you are either Natural Born or Naturalized. And ONLY people who were born outside the USA are Naturalized. In short, the Heritage Foundation book shown above, and the other articles cited and MORE THAN TWENTY APPEALS COURTS ruling on presidential eligibility ALL say that every child born on US soil is a Natural Born US citizen.BTW, since criminals born on US soil are Natural Born Citizens and eligible to become president, it is an absurd notion that the writers of the US Constitution wanted to bar the US-born children of foreigners (the children have not committed a crime, you know). IF they had wanted to bar either US-born criminals or the US-born children of foreigners, the writers of the US Constitution would have said so---but they did NOT say so in either case.The Heritage Foundation book (see quotation above) and the other articles and the chief justice of the USA who swore in Obama and the Republican Party, which did not object to the swearing in, are correct. The "you gotta have two citizen parents (or even one)" theory is wrong.
