There's no doubt polling changed following the surprising result of the 2016 presidential election.
No matter what candidate you voted for, the large majority of national polls showed Democratic nominee Hillary Clinton beating then-candidate Donald Trump. Of course, we know that's not how it ended up.
How are pollsters changing their approach in the 2020 presidential race?
They're saying you shouldn't pay attention to the record number of early voters, which has already eclipsed the entirety of the 2016 election at over 47 million people with just 11 days to go until Election Day.
"We've never seen anything like this," said Siena Research Institute Poll Director Don Levy. "If you look, every day right now there's five million Americans voting."
Of the roughly 50 million Americans that have voted early, Levy said a large portion tend to lean Democratic and have voted for Joe Biden.
But, that doesn't mean a whole lot come Election Day.
"Of those people who have not yet voted or say they're going to vote on Election Day, the president has a strong lead. This is a strange and different dynamic. There's no question before the votes are counted on November 3, the sense will be that Biden's ahead. That he's banked a lot of votes."
The Golden State figures to fall the same way in 2020 as it did four years ago.
"Democrats have a 30-point advantage of the five million votes already cast (by Californians) in this election," said Mark DiCamillo, Director of the Berkeley IGS Poll told KCBS Radio's Doug Sovern. "Californians have to be in the early going voting for Biden. I don't need a poll for that."
