The race for the White House is coming down to who wins the few remaining battleground states – Georgia, Pennsylvania, Nevada and Arizona.

A win in just Pennsylvania or two of the other four remaining states would be enough to confirm Mr Biden as president-elect, barring any legal challenge.

Mr Trump, meanwhile, needs to win Pennsylvania and three of the remaining four states.

GEORGIA – 16 electoral votes
Where things stand:

Biden lead in Georgia of about 1,000 votes.

How many votes are still to be counted: Local officials said on Thursday that around 15,000 votes were left to count, but there has been no update since.

Where are these votes? These were postal ballots mostly from Atlanta and Savannah, which have skewed heavily toward Biden.

PENNSYLVANIA – 20 electoral votes
Where things stand: Biden has overtaken Trump by just over 5,000 votes, from what was once a Trump lead of more than half a million votes.

How many votes are still be counted: Just over 163,000 votes remain.

Where are these votes? In counties won by Hillary Clinton in 2016, so mostly Democratic votes.
