Do you have ANY idea how probability works? If you are going to roll a 6 sided die, and you ask me, "What is the probability that I will roll something besides a 6?" I will tell you that you have about an 83% chance of rolling a 6. If you roll, and you get a 6, it doesn't mean I was WRONG on the probability. It just means your roll fell into that 17% chance of getting a 6.

You can't take the result of one election and decide if Nate Silver is right or wrong in his probability. Instead, you have to take his many predictions and see how accurate they are; do his 90% predictions come true 90% of the time, do his 80% predictions come true 80% of the time, etc.

You can't take one time where he said Hillary had a 70% chance of winning, and say he was wrong because she lost.
