Kennedy, 65, lives in Chicago. But she was a coal miner by trade and, in 2003, worked at Emery County's Co-Op Mine owned by the polygamous Kingston family. She was among the workers who went on strike and then were fired by the Kingstons. Ten months later, they were reinstated when the National Labor Relations Board found the miners were wrongly dismissed for union activity.
She now works at a Wal-Mart in Chicago and is part of the movement seeking a $15 per hour minimum wage.
Kennedy knows she will not win the presidential race — she touts modest hopes of being on the ballot in Utah and eight other states — but she defines victory by a different standard.
"We judge winning by the response we get when we go door to door," she said. "We get a good response. Working people are the only ones who can change things."
It's only a matter of time, Kennedy said, before workers join together in larger social struggles, like those surrounding the police shooting deaths of black Americans.
"We think those things will grow and become much bigger and broader," she said. "The way forward is for us to fight for our rights and to take political power and begin to reorganize this society."
Dale Cox, president of Utah's AFL-CIO, said he agrees with Kennedy's message, but noted that his union has endorsed presumptive Democratic nominee Hillary Clinton.
"Her heart is in the right place," he said. "Workers need to be more organized."
Among the challenges, Cox said, is that Americans are apathetic. "People need to vote for their paychecks, not for what's said on Fox News."
Rocky Anderson, a former Salt Lake City mayor and 2012 Justice Party presidential candidate, said what Kennedy is doing is "absolutely fantastic."
He agrees with her that neither the Republican Party nor the Democratic Party serves the interests of workers.
"The more we can generate discussions on subjects completely ignored by Republicans and Democrats," he said, "the better off we will be."
Anderson argued that the Republicans never have had concern for workers and that Democrats abandoned the working class in the early 1970s.
Anderson agrees with Kennedy that the nation needs a strong union movement, a fair tax structure, educational opportunities and a jobs program.
