Yes: random, unbiased sampling creates noisy subgroups that cancel out. Biased methodological choices, OTOH, may not cancel out. https://t.co/1emtygwg7A — PolitiTweet.org

@Nate_Cohn Is that really different then telling people not to look at cross tabs Bc they cancel out ?

Marist appears to do two things: --they weight by region, which is helpful but insufficient --I *think* they stopped calling out of state cells, which is hard to defend but *could* cancel out not weighting by edu. The hope is two wrongs make a right? https://t.co/8rFBVn5Hb4 — PolitiTweet.org

@Nate_Cohn Can you speak a bit ut more to whatever Marist does that they claim makes the poll the same as weighting… https://t.co/7feSoQM9sU

FiveThirtyEight rates polls based on error v. expected error, and assumes they can take care of bias with house effect adjustments. Several of their top pollsters have long records of systematic bias https://t.co/owFrCsiV81 — PolitiTweet.org

@Nate_Cohn Why does the other Nate give Marist an A+ rating if they don't weight for education?
