A natural born citizen is a natural born citizen...
Yes, and Ted is a natural born citizen of Canada. You can not be a natural born citizen of two countries.
A natural born citizen is most certainly a natural born citizen. You seem to imagine that one must be born in the United States (jus soli) and that is not true. When an American child is born outside the United States to at least one US citizen/parent, jus sanguinis makes that child a natural born citizen of the United States. See Lowell P. Weicker, Jr., George Romney (most questionable of this group), John McCain (whose dad and mom were in Panama engaged in winning WW II), Obozo whether we like it or not assuming he was born in Kenya as his paternal grandmother claims to have witnessed his birth).
Now, a challenge: name THREE issues that you admit are MORE important to you than this Birther business. Just three will do.
