Wilson's father was a US citizen, that is all that counts.<quoted text>
That is right. The US constitution says nothing about dual citizenship status. Since it does not specifically exclude dual citizens from being eligible and since the meaning of Natural Born Citizen includes even dual citizens, dual citizens ARE eligible. And there have already been several dual citizens who were President of the USA, including Thomas Jefferson and James Madison (who had been made full voting citizens of France by the French National Assembly), and Woodrow Wilson who was a dual citizen of Britain at birth since his mother had never relinquished British citizenship when she became a US citizen by marriage.
Until the Civil Rights Act of 1866, which was carried over into the 14th, the states made the citizens and made a mess of it, that is not the case any-longer, is it!
