It’s not in the poll takers or media’s best interest to show a lopsided poll. The more controversial the poll or narrow the race, the more the news sells.
The media is clearly biased and still using push polls to try to move public opinion.
If I happen to let one slip by and I answer it I lie to them. Mostly I don’t answer the phone if I don’t recognize the number.
I am not sure what your point is... because that is exactly what the media and the pollsters are doing. Therefore they must consider it to be in their “best interest”.
