What do the Clintons know about Obama?

Do the Clintons know something about Obama that the rest of us do not know? I have this creepy feeling that they have some doomsday knowledge that can destroy his candidacy but that even they are reluctant to release it, even indirectly. Is that why Hillary remains a candidate when she can only get the Democratic party nomination if Obama implodes. A sudden downfall by Obama seems unlikely. Do the Clintons have insider knowledge? What could it be? Something worse than an extra marital affair, child out of wedlock, homosexuality, financial corruption. These seem quaint by current post Monica standards. Is Obama really a Muslim? He could probably explain away even that. But what if he really is the Manchurian candidate? I have wondered about that for some time. Or maybe he murdered another child while growing up in Indonesia. It would have to be something way out. What do the Clintons know? Maybe nothing. Maybe something.
