"When my husband was president, incomes rose for everybody," she said in Louisville.
But the role the former president would play - perhaps as an economic emissary to hard-hit parts of the country - is more similar to the job he has done as one of Hillary Clinton's chief surrogates on the campaign trail. He often goes where she cannot.
Last week, for example, Clinton sent her husband to the heart of Kentucky's coal country - a place where her candidacy has been met with hostility because some there blame her policy position on renewable energy for job losses in the fossil-fuel industry.
The goal: that Bill Clinton would employ some of the empathy that made him one of the sharpest political operators in the Democratic Party. And he did.
"I was governor when the Ozark mountains where I lived had three of the four poorest counties in America. I get this," he told the crowd last week in Prestonsburg, Kentucky. "I know it's hard when places are physically isolated. I'm not pretending."
He also dropped a hint about a future job in his wife's administration.
"All I'm telling you is, I volunteer that if Hillary got elected president, I would like to be tasked with the responsibility to take you along for the ride to America's future," he added.
