A bunch of people with a strong grudge against 538/Silver wrote some long article about his Brazil Germany prediction, like they had been waiting for him to be wrong about a soccer game prediction for six years or longer or something.
yeah. the thing is, nate silver (personally) doesn't make predictions. he just crunches the numbers and tells you what they say. lots of political folks hate him from the times when 538 came out with polls contrary to conventional wisdom and what experienced political pollsters said, and he was almost 100% right in the end.
