No legitimate pollster takes such directions when it will make them look like idiots. There is a difference in polls only for internal use (which may very well do what you suggest) and those which are released to the public.
This is not being done at the behest of the media but completely voluntary on the pollsters part. They are part of the media and totally biased.
And you know this for a fact? You honestly don’t believe that if someone pays for a poll, they don’t tell the poster what they want to measure?
Yike. Thanks at least for proving that on the Internet, someone will argue about anything. Have a nice day.
