Democratic presidential candidate Hillary Clinton holds a six-percentage-point lead over Republican rival Donald Trump, according to a Reuters/Ipsos poll, the day after she formally accepted her party's nomination for the election.
Nearly 41 per cent of likely voters favour Clinton, 35 per cent favour Trump, and 25 per cent picked "Other," according to the new July 25-29 online poll of 1043 likely voters, which overlapped with the Democratic National Convention in Philadelphia.
The poll has a credibility interval of four percentage points.
The presidential tracking poll reflects a slight change of wording from previous surveys, replacing the "Neither/Other" option given to respondents with just "Other." An internal review had found the word "Neither" has, at times, siphoned support away from one or the other candidate.
Former Secretary of State Clinton delivered an upbeat keynote address at the Democratic convention on Thursday night, as she became the first woman to accept the presidential nomination from a major party.
In the biggest speech of her more than 25-year-old career in the public eye, Clinton, 68, cast herself as a steady leader at a "moment of reckoning" for the country, and contrasted her character with what she described as Trump's dangerous and volatile temperament.
Trump, a 70-year-old New York businessman and former reality TV show host who has never held political office, responded in a Twitter post late on Thursday that "Hillary's vision is a borderless world where working people have no power, no jobs, no safety."
Both candidates were on the campaign trail on Friday, kicking off what is expected to be a hotly contested general election battle.
A separate Reuters/Ipsos survey that provided respondents with the option to choose from Clinton, Trump, Libertarian candidate Gary Johnson and Green Party candidate Jill Stein, has Clinton and Trump tied at 37 percentage points.
Of the alternative party candidates, Johnson came in third with five percentage points, followed by Stein at one percentage point, according to the July 25-29 survey of 1,426 likely voters, which has a credibility interval of three percentage points.
