Rush is right.
Yesterday, Fox News had a stunning poll — that 51% of Americans want President Trump impeached on the Demonrats’ entirely-baseless Ukrainian accusations.
But the Fox News poll is deceptive and bogus because it over-sampled Democrats by as much as 14 points.
Funny how @SpeakerRyan who now helps run Fox News has got them to RIG THEIR POLLS
Check out their polling samples! They aren’t even polling fox viewers!
They are trying to give cover for @GOP to impeach!

In polling, sampling bias is when participants in the poll are collected in such a way that some members of the intended population have a higher or lower sampling probability than others, which means the polling sample is not a random sample in which all individuals are equally likely to have been selected. And so the poll’s results can be due to the (biased) method of sampling, instead of a true reflection of the population.
In the case of the Fox News poll, Democrats were over-sampled or over-selected by as much as 14%. That means the poll was weighted in favor of Democrats by 14 points. All of which renders suspect the poll’s results.
