I don't understand this critique. Do you think no phone poll takers are familiar with the concept of sampling bias?
I believe the criticism is that they aren't dealing with it at all and are just publishing this stuff like it's useful information.
If you look at the live poll page, the effort is to show a lot of the moving parts of this process, including the fairly elaborate weightings they use to try to extrapolate reality from the respondents. I've been pretty critical of this, but I'm curious about @fchollet's take
I respect the effort (I was weighting data just this morning) but wtf is a sample size of 32?
It's a poll in progress. Go to the main page and note that they stick huge disclaimers on it (showing EARLY instead of results) until the sample size hits 450 or so. @nate_cohn can speak to the details
The whole thing is an exercise in educating people about how polling works, including its shortcomings, by showing the process in action. Again, I am a big poll skeptic, but I think the criticisms here are a little facile
