Polls exist to plant false ideas — as fact.
They used to go to the universities to obtain outrageous ideas, but then the Ward Churchills of the world thought they really were credible persons and wouldn’t go away back into the intellectual boonies.
So now the polls exist to plant false ideas and memories into the American public — because they no longer have to pretend to take the Cindy Sheehans seriously — and those others who will overstay their fifteen minutes of fame.
Polls are to mainstream media, what overseas email business propositions are to everybody else.
It’s just that mainstream media takes theirs seriously and think they know something everybody else does not.
