Polling is designed to Shape opinions not measure them.
Exactly. While I wouldn’t want to paint with a broad brush and say that all polls are totally fake, I will say that I never pay attention to any polls at all.
I think that phone calls are made, people on sidewalks are questioned, work is done, numbers are tabulated, and THEN the poll people publish the numbers that they prepared before any of that started — the numbers that are designed to push public opinion is a designated direction: “Oh look! 68% of the people trust Hillary on national security issues! I guess that email server thing really IS a rightwing conspiracy!! Now I know how I feel on that issue!”
