There might have been one or two polls that had Clinton up by double digits a week before the election, but the average poll and the state polls made it look like Trump had a legitimate shot. I think it was something like a 20% of Trump winning which was widely misinterpreted as Clinton winning in a land slide. That was like saying, you need a .200 hitter to get a hit to win the game in the bottom of the 9th or the game is over. No good fan would assume the game was lost at this point. They wouldn't expect a win, but they would stay to watch the finish because they know it has happened before. But ye, I understand that someone who doesn't understand probability might have stayed home instead of voting.
