US election: Joe Biden paints himself as a unifying force ahead of final TV debate with Trump.

He may be ahead in the polls but Joe Biden isn't taking any chances, hammering home how much is hanging on the election to supporters in North Carolina.

"The very soul of our nation is at stake. Folks, as my coach used to say in college, it's go time. It's the most important election in our lifetimes," he said.

Voter complacency could still derail him. Hillary Clinton was also ahead with two weeks to go in 2016.

And this week will likely see a victory for the president, with his Supreme Court pick Amy Coney Barrett expected to be approved by the judiciary committee on the same day Mr Trump and Mr Biden go head-to-head on TV.

The televised debate in Nashville, Tennessee, will see the candidates grilled on topics including "race in America", "climate change", "foreign policy" and "fighting COVID-19".

Their first debate was an uncomfortable, rather chaotic, watch dominated by constant interruptions and widely criticised for the tone and tactics.
