Having failed to predict the results of the Michigan democratic primary — “the biggest polling miss in a primary in modern political history” — the statisticians at FiveThirtyEight.com risk calling their reliability irreparably into question by publishing that nonsensical claim.   Here is the claim in context:

Thanks to an 83 percent to 16 percent win in Mississippi, Clinton gained in the overall delegate count on Tuesday and leads Sanders by more than 200 pledged delegates. Her strong performance in Mississippi also put Sanders further behind his FiveThirtyEight delegate targets. That may not be as sexy as the tremendous upset in Michigan, but math is rarely sexy.

Casanova would have disagreed.
