Democratic Presidential Candidate Joe Biden has extended his lead over Donald Trump in Pennsylvania.

With an estimated 96 per cent of the votes counted, Mr Biden had opened up over a 14,000 vote lead over the Republican incumbent.

Should Mr Biden win the Keystone State, he will have 273 electoral college votes – taking him past the magic 270 number needed to secure victory.

Mr Biden, 77, had trailed Mr Trump, 74, by more than half a million votes at one point in the hours after the polls closed.

Earlier on Friday the state reported it had 50,000 mail-in votes still to tabulate.

Exit polls have shown Mr Biden has a healthy advantage among voters who decided to post their ballots early – which explains why he has been consistently chipping away at the president’s lead in Pennsylvania.
