This means our averages can move *even there hasn't been new polling in a state*. Here's Nevada, for instance, where there's little recent polling but the algorithm is making inferences based on changes in national polls, Arizona and Colorado polls, etc. https://t.co/nLrpwNdA0m https://t.co/5bscmBRWKN — PolitiTweet.org
