Yes, Donofrio did not base his case on where Obama was born.
I've seen good arguments from both sides regarding the issue on natural born citizen and how it relates to having one alien parent, yet, the child is born on US soil. I do not think that it has been defined conclusively in law, when applied to eligibility for POTUS. If it was, we wouldn't be reading the thousands of posts that exist on hundreds of threads, where two different trains of thought about the NBC issue continues to be debated without end.
I believe that the framers of the Constitution wanted zero influence, allegiance or loyalty from a foreign state, in regards to the U S Presidency. My impression is that they set the bar as high as they could; birth on U S soil and birth to two U S citizens.
I'm pretty well burnt out on the back and forth arguments. I plan to stand down until the SCOTUS gets involved. Drive on! ;o)
I believe a child born in this country is a US citizen period.
The laws people cite come from a time before we broke from England mostly.
