There are several categories under the law of those who will be citizens at birth, but that doesn't mean that each has a different type of citizenship or a different “source” of citizenship. The “source” was that they were born and were eligible under the law.
Place the point of a len or pencil on a sheet of paper; make two circles separated by perhaps three inches; labe the circle on the left 'by birth' and the circle on the right 'by statute' ... those are the two basic menas of having citizenship.
In the circle on the left you can label subset circles with 'by the citizenship of the parnets', by 'being born on American soil', by 'both born on American soil and American citizen parents', by 'one parent being an American citizen'
Are you smart enough to cite more than one 'by statute' sub-vategory for the circle on the right? If not, you won't understand the birther issue because you have a blockage of the truth in your twisted mindset.
There is only one position in the Federal Government which requires 'by parents' citizenship and by birth on American soil' ... have a nice evening, obamanoid.
