With more and more presidential aspirants (and/or their running mates) being children of one or more non-citizens at the time of their birth, this book is still relevant despite the misleading title. The title is grossly misleading (intentionally or not, it's not clear to me), since the eligibility issue primarily concerns the Constitutional natural born citizenship requirement (ie, both parents being citizens), not mere birthright citizenship or native born citizenship. Corsi does address the natural born citizenship issue, even mentioning Vattel and natural law, but it's superficial and mixed in with a bunch of birth certificate and other stuff that give so much padding it's hard to know if he's intentionally obuscating or not. Corsi does cover a lot, but not all, of related eligibility flashpoints during the Obama campaign for presidency, but quite often it seems as if he's making the case FOR Obama (while seeming to appear against Obama) by misdirection, misrepresentation, omission, quote-twisting, etc. For ex, he lifts snippets, not even full sentences, from the damning video of the now deceased Percy Sutton, which primarily is of concern due to campaign fundraising sources, but Corsi's omits the entire point of the video and actually misquotes Sutton(!), making it seem about something in the past (partially true) and not the fundraising then going on. In sum, the book is probably confusing for most readers, but still documents a strange time in US history, given Obama's the first (not counting accidental president Chester Arthur) to run for President knowing of natural born citizenship eligibility issues -- even if the general populace fell for the birth certificate and mere citizenship red herrings. With 3rd party possibilities, forthcoming running mate choices, and ineligibile people like Ramaswami, Haley, Cruz, Rubio, DeSantis, Sununu, etc., the protective natural born citizenship requirement will impact how people vote, but no one's talking about it yet, so at least this book, annoying though it is, offers some thoughts.
