Credit:AP The Democratic nominee's exhortation, along with a campaign video depicting headlines of a Trump presidency, stating that "reality has no rewind," came as she and Trump blitzed across the nation's swing states with four days until Election Day as polls show the race tightening. Clinton dispatched her most potent surrogates around the country on Friday. President Barack Obama, Vice President Joe Biden and Senator Bernie Sanders all stumped for Clinton. In Denver, former president Bill Clinton talked about everything - from his wife's work on special education to the credit ratings of millennials - assuring around 500 Democrats that they were on track to win. Clinton has also injected wattages of star power: Jay Z will headline a get-out-the-vote show in Ohio, while Stevie Wonder will play a "Love Trumps Hate" show in Philadelphia. "My name's not on the ballot, but everything we've worked for is on the ballot," Obama said in Fayetteville, North Carolina. "Democracy's on the ballot. I need you to vote. Don't choose fear. Choose hope." Obama continued to assert that Trump is "temperamentally unfit" to be the commander in chief and has a long track record of insulting minorities, the disabled, women and others.

If you accepted the support of Klan sympathisers, if you don't denounce them right away because you're not sure, well that's what you're gonna do once you're in office," Obama said. Here in Pittsburgh, businessman and reality television star Mark Cuban relentlessly needled Trump for potentially not being as wealthy as he claims and for lacking the temperament to be president. Cuban also claimed Trump could be bribed. Republican presidential candidate Donald Trump speaks during a campaign rally in Florida.

Cuban asked. "Do you think he cares about you or his bank account?"

"How can Hillary manage this country when she can't even manage her emails?" asked Trump, who will also campaign in Ohio and Pennsylvania Friday.

Trump called Clinton "unstable" and "trigger-happy," and criticised the withdrawal of troops from Iraq. However, in 2011, Trump had supported the withdrawal of troops from Iraq. Trump's crowds typically yell "lock her up" when the candidate discusses Clinton's emails. The one in New Hampshire took a menacing turn, when one supporter shouted "execute her."

But Trump's surrogates continued to create headaches for his campaign. At the New Hampshire rally, former New Hampshire governor John H. Sununu joked that Clinton's husband does not want to have sex with her.

A small crowd gathered at a country club laughed at the joke. One man shouted: "You mean Bill the rapist?" Trump's campaign has yet to respond to the comment.

While talking about how he plans to win Texas, Trump called the state's agriculture commissioner, Sid Miller, a "wonderful guy." Miller called Clinton a "c**t" in a tweet. Wrong way, go back. Credit:AP Also on Friday, two former aides to New Jersey Governor Chris Christie, who is chairing Trump's transition team, were convicted of all charges related to a plot to create a mammoth traffic jam on the nation's busiest bridge as political retribution. Three people, including the traffic jam's admitted mastermind, testified in federal court that Christie knew about it as it was happening. Christie, on Friday, continued to deny he knew about the plan. The convictions are a coda to a huge scandal in a state where political misdeeds are as common as the traffic jam that started this one. Known as "Bridgegate," the scheme hobbled Christie as his national star was rising and imperiled his presidential campaign, which ended in February. Since then his approval rating has nose-dived in New Jersey, where only about 20 per cent of residents surveyed believe he is doing a good job. But all of this has had little impact on Christie's standing within the Trump campaign, where the governor is tasked with spearheading Trump's transition to the White House should he win. On Thursday, Christie hosted a $US5000 a person fundraiser for Trump's transition team at a law firm office in Washington.

Clinton campaign chair John Podesta said Christie should step down from the campaign. Loading "Rather than just crisscrossing the country and hop-scotching, talking about cleaning up the swamp, he might start by draining his own swamp and asking Mr. Christie to resign as the head of his transition," Podesta said of Trump.
