There's fears of further polarisation in the US regardless of whether Donald Trump wins the election.

The former President's been convicted on all 34 counts of falsifying business records before the 2016 election.

He also faces further legal battles, including his handling of classified documents and his role in the Capitol Hill riots.

Otago University professor Robert Patman fears violence may be possible.

"Either because Mr Trump doesn't win the election - or if he makes good on his promise, he will go after those people, from day one, who incarcerated or jailed Trump supporters for their involvement in the 6th of January."
