For John, BLUF: Nate Silver is as good as it gets. Nothing to see here; just move along.
The sub-headline is:
Groupthink produced a failure of the “wisdom of crowds” and an underestimate of Trump’s chances.The Author is Mr Nate Silver and the venue is his FiveThirtyEight blog. The publication date is 10 March 2017. I commend the article to you.
Hat tip to my Wife.
