Democratic presidential nominee Hillary Clinton has extended her lead over Republican rival Donald Trump to eight percentage points, according to a Reuters/Ipsos poll.
The poll released on Tuesday shows support for Clinton has edged up two percentage points from six points on Friday.
The bump for Clinton followed the Democratic National Convention in Philadelphia last week at which Clinton and her supporters painted an optimistic portrait of America, and came amid controversy over Trump's comments about the parents of a slain Muslim US soldier.
About 43 per cent of likely voters favour Clinton, 35 per cent favour Trump, and 9 per cent picked "Other," according to the July 28-Aug 1 online poll of 1289 likely voters. The poll had a credibility interval of three percentage points.
Trump had a short-lived bump in the polls after the Republican National Convention in Cleveland in late July, when Reuters polling showed him slightly ahead of Clinton for the first time since May.
