The third and final US presidential debate between Donald Trump and Hillary Clinton took place Wednesday night, and once again it was an insult-laden bilious grief pit.

There were a few upsides among Trump's attempts to destabilise a democracy and his accusations that Clinton (who played a large role in the Iran nuclear deal) could start a nuclear conflict with Russia, including his accidental endorsement of her.

Maybe it's because he's feeling the Bern?
