Obama could consult a lunar/solar eclipse calendar and "predict" that if people didn't change their ways, a space dragon would swallow the moon/sun.
When the prediction came true, about 33% of the electorate would be telling the rest of us that we should have listened to him, and it's our fault. About another 10% would be cowering in their basements for fear of the dragon.
