I'm pretty sure 538 were the only ones not predicting a strong EC victory for Hillary. And they kept mentioning how terrible the polls were in Wisconsin and Michigan, and that they had to interpolate based on national polls. And in the popular vote Hillary won by a landslide. So this is a statistics package by the people who best interpreted the available evidence. Missing a 66% confidence forecast happens 1 out of every 3 times, it's not a big miss.
