All the polls before three weeks preceding the election are push polls. IMO
All the entities commissioning the polls have a dog in the fight. The pollsters are either directed to get a specific result or they know what the customer wants and they deliver.
I am at the point of thinking that the pollsters take the job and the money and may not actually do the polling. How wold anyone know? Who watches over the actual process.
These polls are a scam.
Also is it any surprise that WaPo who have assigned 20 journalists to dig dirt on Trump come up with a poll showing Hillary up by 10, far more than any other poll ? These polls are pure horse manure at this point.
