Polls are flawed, overused and abused.
It used to be that the mass media would go to the universities and try to get expert opinion -- or intelligent insight, but since they manipulated and misquoted those people, they refused to "cooperate" anymore. So they had to resort to these polls to give themselves some sense of authority. But it's a sham -- like everything else the mass media tries to pull now.
Just ignore them and keep their ratings plummeting. Talk to somebody intelligent instead.
