So....they're only "right" when they agree with a leftist position??
Polled people are only a snapshot of what the people of the country are thinking, at that particular time. It's not a right or wrong thing, since that requires some 3rd party to proclaim what is right and wrong. If you polled the people now, a majority would be against racial segregation & prohibition. Does that make them wrong now?? Of course, not, since it isn't a matter of right vs wrong. It's a position of what the people believe, at a particular time
