Another interesting thing it helps explain. Our 10/19 battleground polls were... pretty accurate! So were the state polls conducted from Jan-Mar 20. Now, maybe these polls were just as bad--and Trump actually led big back then! Or maybe... the bias started since then https://t.co/t6pY7fcb8O — PolitiTweet.org
