PHILADELPHIA (FOX 13) - Democrats will turn to former president Bill Clinton to make the case that their party should be trusted on the economy.
It is a role he has relished since 2000, when after eight years as president, he became the single figure Democrats turned to, to argue they understand how to fix tough times.
"I remember a child telling me her father broke down at the dinner table because he lost his job," Bill Clinton told the convention in 2000.
His rallying skills will again be necessary.
A June CNN poll found 51-percent of Americans trusted Donald Trump, over Hillary Clinton, on the economy. Gallup says 61-percent think the economy is getting worse under Obama.
At the 2004 convention, Clinton argued Republicans gave far too many tax cuts to wealthy people like him.
"They chose to protect my tax cut, while cutting 140,000 unemployed workers out of their job training programs, 100,000 working families out of their child care assistance," Clinton said.
In 2008, the party turned to Clinton as the housing and stock markets were crashing. He used nostalgia for the 90s.
"Look what happened," he said of the Republicans. "They took us from record surpluses to an exploding debt. From over 22 million jobs to just 5 million."
At the heart of his reputation as an effective speaker are his knowledge on policy and his ability to boil down numbers - two things which can be expected of his Tuesday night DNC speech.
In 2012, Barack Obama was being ripped by Mitt Romney, a onetime business owner who centered his whole campaign on Obama's supposed lack of economic understanding. Again, the party turned to Bill Clinton.
"In those 52 years, our private economy has produced 66 million private sector jobs. What's the job score? Republicans - 24 million, Democrats - 42 [million]," Clinton said in that speech.
The difference this time is - Bill Clinton's reputation is in the spotlight, but not the perceived good parts.
Trump has tried to force discussion of Clinton's impeachment, philandering, and foreign donations to his foundation.
And now, his wife is the nominee.
