The Times/Siena polls were often weighted on party x primary, but they were as bad as everyone else's polls. And one thing that seemed to help other polls--weighting on self-reported 2016 vote--would have pushed us even farther toward Biden — PolitiTweet.org

@rp_griffin i think it's entirely plausible that this issue is deeply related to the problem. we've always weighted on primary vote history, but perhaps we fail to reach a representative group of less-engaged, non-primary voters, so weighting doesn't help — PolitiTweet.org
