Actually, they are scientific and they are true. They are nearly 100% correct in the last 40+ years and in this primary season every one of them have been correct.
Actually I (and most others) lie at each one of the questions. 1. Republican or Democrat? Dem. 2. Who did you vote for? Hillary. 3What age are you? 50-55. etc. etc. People like me lie to screw them up. Others lie so the pollster views you better ( I voted for Obama cause I ain’t no raciissss..). There can be no proof these asinine questionnaires are true unless there is a statistical difference of + or -56 points.
