I would hope people on this board would understand statistics. Silver gave Trump about a 1/3 chance of winning, and he said the outcomes could run from a Clinton blowout to a narrow Trump victory, which is what happened.
If people were interpreting his "33%" as "0%", despite all his warnings and explanations about what was possible, that's their problem, not Silver's.
