Way back in the day, you needed a little bit of evidence to claim non-response bias was at play. Stability in the YouGov poll, or another party weighted poll, would offer some evidence--even if not conclusive evidence, given other methodological differences — PolitiTweet.org

Anyway, partisan non-response bias is a real thing. But the idea that there's basically no change in public opinion, only partisan nonresponse bias, is lazy thinking. And given partisan bias of this website, it basically just means people saying nothing bad ever happens to Dems — PolitiTweet.org
