Democratic presidential candidate Hillary Clinton holds a five-point lead over Republican Donald Trump in the latest Washington Post-ABC Tracking Poll released early on Sunday.

In the Post-ABC poll released on Friday, Clinton led Trump by 47 per cent to 44 per cent.

Clinton had an advantage in affirmative support, the poll said, with 55 per cent of backers saying they are mainly supporting her, compared with 43 per cent of Trump voters. More Trump voters say they ‘mainly oppose Clinton.’
