AP calls presidential race for Joe Biden as Pennsylvania lead grows

Four days after Election Day, Joe Biden is projected to win enough electoral votes to be the next president of the United States, according to the Associated Press. 

Biden, who was the projected winner of Minnesota on Tuesday, had been trailing President Donald Trump in a few battleground states where results weren't complete because officials were still counting votes. 

On Saturday morning, Biden had a projected 264 Electoral College votes, just six votes shy of the 270 needed to win and the Associated Press reported he had overtaken Trump in the vote count in Pennsylvania and George, but the votes in those states were still too close to call. 

However, despite the AP's call, there remained uncertainty over whether Biden would actually win Arizona. In any event, it doesn't matter, as the latest results put him 30,000 votes ahead in Pennsylvania, giving him 20 electoral votes, taking him well past the 270 need.

There remain votes to be counted in Pennsylvania, but the vast majority are from heavily-Democratic areas, and it's likely that his lead will grow even larger.

Saturday morning, millions of ballots were still being tabulated, Biden had already received more than 74 million votes nationally – the most in history, the Associated Press said.

Even if Trump wins the remaining 4 states that still haven't been called – Georgia, North Carolina, Alaska, and Nevada – and even he wins Arizona after all, he won't have enough Electoral College votes to win. 

This came after Biden narrowly beat Trump in two other battleground states in Wisconsin and Michigan this week. 

The results are still not official. States need to finalize the results of the popular vote, which is done days and sometimes weeks after Election Day, and then electors will cast their votes in the Electoral College next month.

What's more, Trump has challenged and is expected to continue to challenge the results of the election.

Trump has attempted to undermied confidence in the election due to delayed results (the FBI previously warned people might try to do this if results aren't available on Election Day), falsely stating Democrats are trying to steal the election as local election officials work to count every legally cast ballot, which is required by law. 

Many of his tweets over the past few days have come with an alert that the content is disputed or misleading about the election.
