Super Tuesday: More US primaries craziness from Trump, Rubio and co.

‘I’ve never seen a human being sweat like he sweats.’

‘He should sue whoever did that to his face.’

They are not the comments of self-made social media commentators.

They are not barbs traded in a schoolyard.

Have a listen to this report from the US to Ross and John to hear what the Republican race has descended into.
