Repeat from another thread:

Iowa will probably have 150,000 - 200,000 GOP caucus-goers. More than half, up to 70%, are regulars who have attended a number of caucuses over the years, and the party knows them by name and address.

‘Random’ polls rely on voluntary answers from a random population, not from known names and addresses. The problem with these polls should be obvious.

Margin of errors are at least twice what pollsters will admit. And that’s for honest polls, not push polls, which, of course, show up on demand to fit a MSM meme.

" More than half, up to 70%, are regulars who have attended a number of caucuses over the years, and the party knows them by name and address."

So, you're saying the Iowa Republican Party gave Quinnipiac a list of names and numbers...and they called a subset of that list?>p>Makes sense.

It would cost far too much time and money to do it randomly. And right.
