It looks like the more people they poll -the better Trump’s numbers are. So, the secret is in polling fewer people to get a lower average??
Well sure. If you as a pollster know who to poll as in all likelihood you know who they are supporting. They know the demographics of a neighborhood, or they’ve polled these same people before only to re-poll them later knowing that they will likely give you as the pollster the same results.
The pollster works for NBC/WSJ and these guys hate Trump as that in itself should disqualify them as not being unbiased. It doesn’t take much imagination that the pollster is going to tell their employers who are anti-Trump crazies what they want to hear.
