” Doesn’t it follow that if he’s lied about everything else [as Corsi and Cashill have so recently and effectively documented], he lied about his BC too? “

Absolutely.
His history of pathological lying, corruption , dishonesty , shady politics , arrogance and missing records makes it more likely that he would lie
about his birth origins .
It defies logic and common sense that for just this one instance,
he would abandon his usual pattern
and decide to behave ethically.
This is buttressed by the fact that he has still not released his
birth certificate and other “ original vital records .”
The same “ original vital records “ ( plural ..hmmmm ) that Fukino stated in her second statement
were “ maintained on file by the
Hawaii State Department of Health .”
And then she breezily declared Barry to be a “ natural born American citizen.”
Without citing what evidence or expertise she used to come to that conclusion.

You said it well. If there is one thing I have noticed about Malignant Narcissists, it's that once they establish their pattern [which always, always includes pathological lying] they stick to it come hell or high water. In fact, in Obama's case, it's been established that he lied repeatedly about his birth narrative. The only thing we don't know is the extent to which he lied. My guess: re: just about every aspect of it. Of course we won't know for certain until more information comes out. Which eventually it will.
