The polls did NOT fail. Plot below shows @FiveThirtyEight's forecast plotted against the actual result. We do see an overall bias of about 3%. But this is not unusual and was accounted for. 92% of the confidence intervals covered and only GA, NC, & FL were in the wrong quadrant. pic.twitter.com/p8ikx0O9Zt
