I do. I'm wondering about a lot of other people.
You took the statement out of its context. The poster asked whether the Chief Justice would *knowingly* swear in an imposter.
You see, he couldn't do it knowingly if he wasn't convinced of the proposition. Since nobody has proved it, he wouldn't be convinced. It had nothing to do with Obama's obligations.
I doubt if there is a judge alive who is not totally familiar with Obammy's reluctance to produce a bona fide certificate of live birth. Therefore, that's all the judges have to know -- the fact that Obammy was not qualified because he failed to produce the required birth certificate. Knowing that, there is no good reason to administer the oath of office to someone with no valid documentation.
Like I said, the onus is on Obammy for not producing documentation -- not on anyone else for not proving Obammy wasn't fit to hold office. It's no one else's job except Obammy to produce or go away. Doesn't take a whiz kid to figure this out.
