The outcome of the US presidential election hangs in the balance as several states continued to count their ballots, including some of the most competitive battlegrounds where the tally could take days to complete.
The report said in 2016, around 58.3 million pre-election ballots were cast, including ballots in the three vote-by-mail states that year. That early vote accounted for about 42 per cent of all ballots cast in the 2016 presidential election.
The 77-year-old former US vice president will become the 46th president of the United States, CNN reported, after a victory in Pennsylvania, the state where he was born put him over the 270 electoral votes needed to win.
