The argument based on his dad’s citizenship is different than BO’s citizenship. Donofrio is trying to argue BO’s British citizenship.
I feel with great certainty that a court in the 21st century is going to take into account the fact that a woman could get knocked up by a foreigner and have that foreigner abandon her and not penalize the child if born in the US - whether they would differentiate between whether the alien married her or not is another thing.

It’s obvious to me that the term Natural Born Citizen was meant to hold the President to a higher standard. It is used nowhere else. I think they wanted to make certain the President had no divided loyalties. It is clear from his books, in his own words, that he does have divided loyalties. The entire book is about his black half and even titled as such. It’s almost as if he was abandoned by him, so all of the negativity is directed toward whites. I assume you have read the book. Can you dispute that he clearly has divided loyalties?
