At a rally in OH on Monday, the candidate reiterated the same remarks, claiming Clinton only views people of color as votes and not "human beings worthy of a better future".
Farage then reacted to reports that polls on the morning of the Brexit vote showed the "leave" side was substantially behind despite ultimately ending the day with a victory.
Farage said he would not actually endorse Trump because he did not want a repetition of what he called President Barack Obama's interference in British affairs when Obama urged Britons to vote to remain in the EU.
"Everybody said we'd lose (but) we did it", he told a cheering crowd.
Trump has support from online ultraconservative writers, activists and trolls-the so-called "alt-right"-and from some white supremacists including former Ku Klux Klan leader David Duke, who is running to represent Louisiana in the US senate".
"I think that you have a fantastic opportunity here", he told the crowd. But you know I get it, I get it.
"But I will say this: If I was an American citizen, I wouldn't vote for Hillary Clinton if you paid me", he said, referring to the Democratic Party nominee. "I wouldn't vote for Hillary Clinton if she paid me".
Farage stepped down from UkIP's leadership in late June, days after some 52 percent of Britons chose to end the UK's membership in the European Union (EU) during a referendum. "The vast majority of our members of Parliament supported staying in the European Union", he said.
He was the subject of controversy in the hours after the vote, when he stepped back one of the key "leave" pledges that Britain should use the 350 million pounds a week it sends to the European Union to fund the National Health Service instead.
Critics have repeatedly accused Trump of pushing racist and bigoted views during his campaign, including calling for the U.S.to build a wall across its Mexican border to stem illegal immigration and to fight terrorism by temporarily banning Muslims from entering the U.S.
And he dismissed the hostility of many Republican politicians towards Mr Trump as irrelevant, insisting instead that he should mobilise grassroots support. According to the BBC, Farage has used this perception to attack political rivals that he was able to paint as too entrenched in the political establishment, a similar strategy that Trump used to defeat his opponents during the primaries.
Farage, the former leader of the UK Independence Party and one of the main proponent of the Brexit, appeared with Trump on stage in Jackson to compare the British EU-exit vote and the magnate's campaign.
