Democrat Joe Biden leapfrogged Donald Trump to take a major lead in one of the key battleground states Pennsylvania. Currently, he is 5,587 votes ahead of President Donald Trump, reports AFP. 95% of the estimated vote total has been reported.

A victory in this key battleground state would push him past the threshold of electoral votes needed to win the White House, AFP reported quoting US media.

More ballots are yet to be counted, but shortly before 1400 GMT, CNN and The New York Times reported that Biden had moved ahead of incumbent President Donald Trump by more than 5,500 votes.

Biden currently has at least 253 electoral votes. The magic number is 270. If he wins Pennsylvania — a state won by Trump in 2016 — and its 20 electoral votes, he would pass that threshold.

Biden is also currently in the lead in key states Georgia and Nevada.

There are 130,000 ballots left to count in Pennsylvania, many from Democratic-leaning areas. Allegheny County (Pittsburgh) has at least 37,000, and the Philadelphia suburbs have about 20,000, New York Times reports.
