Pennsylvania's Secretary of State says the counting of its remaining mail-in ballots could be completed on Thursday.
Business Insider reports Joe Biden has been cutting into President Donald Trump's lead in the state as mail ballots have been counted.
In 2016, Trump carried the state by less than 1 point.
That razor-thin margin made it a top priority for Democrats to win back in 2020.
If Biden wins Pennsylvania, he'll secure the electoral college majority necessary to win the presidency.
So far, Insider and Decision Desk HQ projections say Biden has secured 253 electoral college votes.
Trump has so far won Florida, Iowa, Ohio, and Texas.
Races in Arizona, Nevada, and North Carolina remain too close to call, although Fox News and the Associated Press have called Arizona for Biden.
