Clinton and Trump tie in a poll that includes Gary Johnson and Jill Stien

Reuters/Ipsos poll was phrased to include no other candidate in results

The 'bump' in poll came one day after the Democratic National

Democratic presidential candidate Hillary Clinton held a six-percentage-point lead over Republican rival Donald Trump, according to a Reuters/Ipsos poll with new wording that was released on Friday.

The poll 'bump' came just one day after she formally accepted her party's nomination for the November 8 election.

Nearly 41 per cent of likely voters favor Clinton, 35 per cent favor Trump, and 25 per cent picked 'Other', according to the new July 25-29 online poll of 1,043 likely voters, which overlapped with the Democratic National Convention in Philadelphia.

The poll did not include third-part candidates including the Green Party's Jill Stein or Libertarian Gary Johnson

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.
