Original intent of the 14th Amendment
For those REALLY INTERESTED I recommend the discussion in that article of the 1889 Supreme Court case: Wong Kim Ark that is used by the Libs to justify the current Born in the USA = Citizen of the USA ruling.
The applicability or non-applicability of this case to our current situation hinges on the issue of legal versus illegal immigration. The article argues that the intent of the Wong Kim ARk ruling was to insure that citizenship would be awarded to the children of legal immigrants. It was never intended to apply to the children of people who sneak over our border.
At the time of Wong Kim Ark there was no such thing as illegal immigration.
Correctly interpreting the 14th would mean Obama is not a citizen.... er, oops.
