Whether there is a legal record of the Kezia marriage to Obama Sr would be a matter for discovery.
Kezia is alive and can testify that she married Obama Sr, which is not hearsay!
RummyChick has provided lots of leads that indicate that Kenyan law recognizes tribal marriage and the US (and HI) would recognize Kenyan marriages and thus refuse recognition to a bigamous marriage by Obama Sr and SADO.
All of this would be subject to litigation in Kenya and the US that would likely take years and be subject to corruption in both Kenya and the US.
I don’t believe any of us know how all of this would shake out legally. But I have no expectation that BO will be declared ineligible based on 1948 BNA dual citizenship.
On the other hand, if evidence proves Obama was born outside the US, he is toast!
Of course, like all of these tangents, none of it changes the fact that the individual known as Barack Hussein Obama II, whose legal, biological father was a nonresident alien, does not meet the definition of natural-born citizen under demonstrable original intent of the Founders, as required for eligibility to the office he now holds.
That is known, right now. No wild goose chases in Kenya or England. No interminable delay of years, enabling the precedent to be set, allowing a Constitutionally ineligible President to complete a full term of office.
