Go back far enough to set up a Manchurian Candidate, and if the overlords were smart enough to predict enough change in racial attitudes to make a black President possible, rather than just picking a white kid, well, I for one welcome our new overlords. But of course, they must have known I would.
Seriously, the organizational and mind-control skill it would take to make any of the teabagger conspiracy theories work would make the conspiracies redundant. Or at the very least, there would be MUCH simpler ways to do them.
