As Americans Await Winner, Biden Overtakes Trump in Several Key Battleground States VOA News Democratic candidate Joe Biden has moved closer to claiming victory in the U.S. presidential election as updated vote counts erode President Donald Trump's leads in Georgia and Pennsylvania. Biden currently leads in the popular vote as well as the Electoral College count, 253-214, with a majority of 270 needed to claim the presidency for a four-year term. Vote counting is still under way in four states that will decide the election: Arizona and Nevada, where Biden is ahead; Pennsylvania, where Trump's early lead has, as of early Friday, decreased to 18,000 votes, and Georgia, where Biden has pulled ahead by 917 votes. IFRAME: [1]https://projects.voanews.com/us-election-map-2020/?lang=en&voa In the U.S. Electoral College system, the popular vote winner in each state -- with two exceptions, Maine and Nebraska -- receives all of that state's electoral votes, which are allocated on the basis of population. Meanwhile Trump, without evidence, Thursday accused Democrats of engineering massive fraud and irregularities to prevent him from winning reelection as president. "This is a case where they are trying to steal an election, they're trying to rig an election, and we can't let that happen," said Trump during a news conference. In contrast, Biden earlier in the day urged patience while states tabulate the record number of votes, more than 150 million, cast in this year's election. "Each ballot must be counted. And that's what we're going to see going through now. And that's how it should be. Democracy sometimes is messy," Biden said during a briefing. Counting under way If Biden holds his vote leads in Arizona, with its 11 electors, and Nevada with six, he will reach the 270 Electoral College majority and become the country's 46th president at his inauguration in January, no matter the outcome in Georgia and Pennsylvania. Trump needs to hold all the states he has been leading in and pick up either Nevada or Arizona, in each of which Biden is currently leading. In Pennsylvania and Georgia, Trump's lead shrank as the vote count continued. Pennsylvania Secretary of State Kathy Boockvar said Thursday the remaining votes being counted are almost entirely mail-in ballots. So far those have significantly favored Biden.
