The polls got California wrong, too: Hillary Clinton beat Donald Trump by a lot more than they predicted.
Highlighting a growing political divide between California and the rest of the nation, Clinton is on course to defeat Republican Donald Trump by 29 percentage points this election, earning 62 percent of votes counted so far to 33 percent of votes for Trump.
The last time a presidential election was that lopsided in California was in 1936 when Franklin Roosevelt beat Alf Landon by 36 points, according to data from uselectionatlas.org.
Clinton so far has bested Barack Obama's margin over Mitt Romney in 2012 by six percentage points. She will win millions more votes in California than Trump.
Most polls had Clinton beating Trump by 20 to 25 percentage points.
The huge margin she has run up in California is a key reason why she is expected to win the popular vote, even though she will lose the Electoral College vote and the presidency.
Under the Electoral College, Clinton's margin of victory in California is irrelevant. She would earn the state's 55 electoral votes if she wins by three votes or three million.
There are still a few million votes to be counted in California as counties process ballots mailed in by voters close to election day.
This chart shows the most lopsided presidential elections in California history. It assumes Clinton will maintain her margin from today once all votes are tallied.
