Forecasts vs Actual
Polling has always been an inexact science, but some of the forecasting models have become fairly sophisticated. They do simulations with polling results, taking into account things like sample size and historical accuracy.
None of the forecasts predicted the result, a Trump Win, in the 2016 election.
See Forecasts - The New York Times.
None of the 19 states considered solid Democratic states, e.g. Hawaii, Vermont, New York, Massachusetts, California, ... went Republican. It was the 15 or so states considered battleground states and specifically Michigan and Wisconsin where Clinton was considered to have a 3.5% - 6% lead that made the difference. Polls in Florida and North Carolina went back and forth in the week before the election.
RealClear Politics came the closest getting 4 states wrong and FiveThirtyEight got 5 states wrong, but they tipped the election.

Other Forecasts:
At the end of September American University Professor Allan Lichtman predicted Trump would win.
He has correctly predicted the results of every presidential election since 1984
using his system of 13 "keys." His book,
"Predicting the Next President: The Keys to the White House" explains how he does it.
If 6 of the 13 keys are true he predicts that party in power will loose.
On Nov. 3 he was on Fox news and hedged his bet because of Trumps uniqueness,
but said he would stick by his prediction that he would win.
Summary:
Trump was the first Republican since 1988 (H.W. Bush - Dukakis) to win Michigan, Wisconsin or Pennsylvania.
At What A Difference 2 Percentage Points Makes | FiveThirtyEight Nate Silver says,
A 1% shift of popular vote from Trump to Clinton (a 2% shift in the spread) in Michigan, Wisconsin and Pennsylvania would produce add 46 electoral votes to Clinton making her the winner.
The GOP has learned that there's a bigger market for populism, and a far smaller one for movement conservatism, than many of us imagined.

But whereas Obama won Iowa by 10 percentage points in 2008, Clinton lost it by 10 points.
