Hillary Clinton has given voters another reason to oppose Republican Donald Trump: she says his 'distressful' campaign is causing people to lose sleep, develop stomach problems, and suffer headaches.

Clinton made the sick attack on her rival after going through her usual list of people he has insulted. Campaigning in Raleigh, Clinton said Trump had 'demeaned women, mocked the disabled,' and 'pitted people against each other.

Then, she lingered on the issue, talking about 'how distressful its been' for voters she has spoken with.

'I know there are a lot of people that are upset about what’s gone on in this campaign, aren’t they?' she asked a crowd, winning signs of agreement.

CAN YOU KEEP YOUR DOCTOR? Hillary Clinton says Donald Trump's attacks have been 'distressful' to a lot of people – even causing stomach aches

'I’ve had people say that they can’t sleep, that their stomachs are bothering them, they have headaches,' Clinton continued.

Then she referenced a quote by first lady Michelle Obama, that the presidency ' doesn’t change who you are – it reveals who you are.'

Clinton's gut punch on her rival came on a day when she came out with another all-out attack, raising the issue of a KKK newspaper that endorsed Trump under a headline that used his 'Make America Great Again' slogan. The Trump campaign denounced the endorsement, although at other times in the campaign Trump has retweeted white nationalists.

Days ago, Clinton accused Trump of 'assaulting' women, and campaigned with former Miss Universe Alicia Machado.

After early signs that she may not be getting the numbers she needs out of younger and minority voters in battleground North Carolina, Clinton brought musician Pharrell Williams and former rival senatorBernie Sanders to fire up young people, minorities, and women voters.

'So tell me this, North Carolina: Are you really really happy that we’re here tonight?' Clinton told a cheering crowd of supporters.

Clinton hailed 'these two extraordinary men' after getting saluted by both of them. Then she borrowed President Obama's slogan, saying, 'I feel all fired up and ready to go for the next five days.'

Introducing Clinton, sanders returned to the wealth and equality based themes of his campaign. 'We are not gonna become an oligarchy,' said Sanders, whose attacks on income inequality allowed him to run a spirited primary against Clinton that had the Clinton operation running scared.

'And this campaign is not a personality contest. We’re not voting for high school president,' Sanders told a cheering crowd of about 4,000 in the university town.

He blasted the 'grotesque level' of income inequality, and said 'nobody can make it' on the $7.25 federal minimum wage, which he called a 'starvation wage.'

He added, 'You can't make it on $10 an hour,' he said. Sanders noted there is one candidate 'who has pledged to make the minimum wage a living wage' – Clinton, although he didn't mention the 'fight for $15.'

In a campaign that has lately devolved into a series of charges of sexism, assault, and corruption between Trump and Clinton, Sanders ran through the gamut of liberal issues he campaigned on, including paid family leave, rebuilding 'crumbling infrastructure,' and other issues he campaigned on.

He said Clinton would deliver 'tuition free' college – which he termed a 'pretty revolutionary idea.'

Williams, who gushed about Clinton in an appearance on 'Ellen' this month, indicated that he knows something about the 'Art of the Deal.'

He held a brief tarmac meeting with Clinton and met young voters with her – and says Clinton made 'commitments.'

LETS MAKE A DEAL: Clinton said she would do 'everything I can' to deliver arts and music education to at-risk kids

'This country hasn’t always been fair to all people, especially my culture,' Williams said. 'But I think Hillary’s going to help fix these wrongs.'

'She’s made some commitments. She made some commitments,' he continued. 'Whether it’s pay equality for women, free public college tuition ... and very important to me, addressing the mass incarceration issue of 1994,' Williams said.

Bill Clinton signed the crime bill in 1994 that included 'Three strikes, you're out' sentencing – an action that became an issue for Clinton to overcome in her primary campaign.

'She’s made a commitment to me. Three strikes, all those things. We’re gonna deal with all those things,' Williams said.

Speaking after Williams, Clinton introduced an additional issue into the mix – music and arts education.

'I’m especially pleased to have Pharrell here,' she told the crowd, which lit up for the 'Happy' star. 'Every time I see him, which is not often enough, we always have a good conversation like we did before this event.'

'He always gets you to think. Not only is he a world class talent but he is a passionate advocate for issues,' Clinton gushed.

Then she added: 'I’m going to do everything I can help him to deliver giving kids who are at risk access to education and arts programs that they deserve to have.'

Clinton brought the hit-maker to greet about 100 students at North Carolina Central University. The crowd grew before the duo left.

The two posed for selfies and Pharrell flashed a pieace sign, urging his fans to 'vote for Hillary.'

'Get out and vote,' Clinton told the students. 'I just need you to got vote.'

The latest Quinnipiac Unversity poll in the state has Clinton leading by just 47 to 44 per cent, with Libertarian Party candidate Gary Johnson at 3 per cent.

Clinton is counting on the nod from Sanders to help drive up turnout among young voters. Media reports have revealed a drop off in early vote totals compared to 2012.

The importance of the battleground was made plain Thursday night as Clinton's campaign plane landed at Raleigh-Durham International Airport just before sun down.

Pharrell Williams caught the press off guard when he sauntered up the jetway to board Clinton's plane. Olympic skater Michelle Kwan, another Clinton backer, also boarded the plane at one point.

As Clinton and the hit-maker were chatting, while reporters were waiting to snap pictures of the pair, Trump's Boeing-757 landed on a nearby runway.

Clinton was there to attend her evening rally in Raleigh, while Trump was headed to Selma, North Carolina for his event.

The gathered media then got to shoot well-staged photos of Clinton and Williams getting into the candidates SUV to go get out the vote.

Reporters aboard Trump's plane, who typically follow just one candidate from rally to rally, were able to film and photograph Clinton's motorcade.

Not long after, Clinton's press corps, which had to take a slight detour to pick up additional members, were able to view Trump and his entourage exiting the mogul's jet. That is something Trump's own press corps doesn't usually get to witness, because the candidate does not fly on the same aircraft as the reporters who cover him.

Pharrell made clear his support for Clinton in an appearance earlier in October on the 'Ellen' show.
