Was it really his grandmother he lived with. No one really knows anything about these people. Well, some do for sure. I imagine that Putin knows it all, along with Pelosi, the Clintons and scores more in Congress.
Who knows. With Obama, it could be anything.
I think that’s one of the things that added to his Antichrist vibe: nobody is supposed to know where the Antichrist comes from. And it’s clear nobody knows where Obama comes from, probably not even himself (it probably depends on whatever answer he would think most useful at the time).
