Minor v. Happersett is being used by birthers to "prove" Barack Obama is ineligible to be president.  They are counting on "At common law, with the nomenclature of which the framers of the Constitution were familiar, it was never doubted that all children born in a country of parents who were its citizens became themselves, upon their birth, citizens also. These were natives or natural-born citizens, as distinguished from aliens or foreigners." leaving out "Some authorities go further and include as citizens children born within the jurisdiction without reference to the citizenship of their parents. As to this class there have been doubts, but never as to the first. For the purposes of this case, it is not necessary to solve these doubts."  To make their case stronger, they have changed "parents" to "two parents". I think this should not be allowed as it is not in the decision.
