Here is a simple question.
Did the majority opinion AND the Dissent of Wong Kim Ark indicate that the majority opinion was that the 14th Amendment was declaratory of the Common Law Doctrine on citizenship.
WKA was not found to be a "natural born Citizen", only a "citizen."
And the state of Indiana case of Ankeny confirms that the WKA court did not find WKA to be a "natural born Citizen."
