I also did research, even though my civics class had stated for the purposes of Presidential eligibility, it had to be 2 citizen parents and born on American soil. Also no dual citizen status allowed.

Then they noted that it was not necessary to determine the answer to that question for the case in front of them. Too bad they didn’t take the opportunity to settle it right then and there.
I didn’t really participate much in those discussions - I felt he was so unqualified and his politics so radical, that was what needed to be questioned the most, since the press had already succeeded in labeling the birth issue as nutty.
