Well part of it anyway, but the other part doesn't depend on the BC, except to prove his legal father was BHO Sr., a Kenyan national and, at the time, a British National. Not even a permanent resident alien, just a guy on a student visa.
But that said, he's concealing something and not being born in the US is the most obvious thing. Being a bastard would have helped him with certain constituencies, ditto his father being some black 60s radical.
Maybe just the embarrassment of having his "history" shown to be pure bunk? Or that his legal name is Barry Soetero? Who knows? But he's hiding something.
If he was truly born in Hawaii, I think it would end it. Going to Indonesia as a child was out of his control.
Yes, what is he hiding?
