Nate Silver, founder and editor-in-chief of FiveThirtyEight –
As of our most recent Election Update this weekend, I noted that polls since last week’s debate had been — this is a scientific term — “pretty weird.”
Well, it’s time to revise that statement. There have been a whole bunch of new polls over the past couple of days. And they’ve been not just pretty weird … but really weird. As far as I’m concerned, that means it’s exactly the sort of time when it’s helpful to take an average instead of fixating on individual polls.
On balance, national polls have been pretty good for Bernie Sanders — but there’s a lot of variation from survey to survey.
