@PollsAndVotes And if we had not weighted by party/education, like most of the you've seen, our results would have been: Biden+5 Sanders+3 Warren+1 (I should note that we stratify our sample on party reg x region, which would tend to diminish the importance of weighting on party) — PolitiTweet.org

@PollsAndVotes (IE: in FL, our respondents are 37% dem, 35% rep by registration, since that's the state tally; it is possible that if we just collected sample without stratification, like most polls, the underlying sample may have been more D/R in unknown ways) — PolitiTweet.org
