Show me the constitutional reference, please?
A mere law does not overrule the constitution, the constitution is the SUPREME LAW OF THE LAND.
The US has never used a strict version of either, but instead has generally used a hybrid definition of both. The first Congress (1790) defined "natural born citizen" with an exclusion based on the father's nationality. Later law put it the opposite way in cases of illegitimate children, where the mother's nationality is the one that mattered. The government didn't want citizen claims made by the illegitimate children of our military members serving abroad.
The original intent of the clause had to do with holding office while having an allegiance to a foreign sovereign nation. Far as I can tell, Obama's only allegiance is to himself.
In an interesting twist to this topic, McCain was born in Panama, where his father was stationed when he was born. His natural born citizenship came about through a law passed after he was born that had a retroactive provision that fit cases like his.
