CNN's Washington Bureau Chief Sam Feist explained how CNN makes projections and why 2020 is different to other years.
"This year's different than any other year. Everything in the country is different because of [Covid-19,]" Feist said.
One of the biggest changes in 2020's election rhythm is the massive uptick in mail-in ballots.
"It takes longer to count mail-in ballots. You have to open the envelope, open the outer envelope, check the signature, scan the ballot. It takes a while," he said.
Certain states, including Florida and North Carolina, have been processing mail-in ballots for weeks, with early counts likely to favor Democratic nominee Joe Biden.
Elsewhere, including Pennsylvania and Wisconsin, mail-in ballots aren't tabulated until after voting closes, a detail that could favor President Trump initially.
"Those states may favor Donald Trump late into the night, until those mail-in ballots go in, and then the count will even out a little bit," Feist said.
A look at how CNN makes projections: Wolf Blitzer announces that the network has projected this or that candidate will win a particular race.
The process that leads to Blitzer saying those words is careful and complicated. It involves both real-time results and information from exit polls. CNN, NBC, ABC and CBS work with the polling firm Edison Research in what is known as the National Election Pool for results and exit polling data. Fox News and the Associated Press have a separate arrangement.
