OK, a couple more pollster ratings tidbits: Live caller polls (which place calls to cellphone + landlines) polls continue to outperform online polls. And online polls continue to outperform IVR (robopolls), although the distinction between IVR and online is blurry now. https://t.co/NKDIzmPbre — PolitiTweet.org
