In 2008, Bill Clinton's acerbic role as a campaign surrogate overshadowed Hillary Clinton and ultimately undermined her presidential campaign. In 2016, he's being used more as a storyteller and less as an attack dog.

A new video showcases his stump speech testifying to Hillary's record as a "change-maker," an implicit rebuke to the Bernie Sanders charge that she can't bring about real progressive change.

Backed by dramatic string music, the ad mixes slow-motion footage of Bill Clinton mingling with voters with speech excerpts. Nearly every word Bill Clinton says is written on the screen, showing that the Clinton camp has finally caught up on how to use the Facebook machine.

Setting up the case for Hillary, he says, "But there's a big difference in who can do, and who can't."

Bill Clinton Says Hillary Is "A Change-maker... Not a Change-talker."

"She's the single best change-maker I've ever met in my life. And we need a change-maker." In another implicit swipe at Sanders, Bill Clinton adds, "Not a change-talker, a change-maker."

He dons the mantle of raconteur, sharing a tale of when Hillary worked on education reform while he was governor of Arkansas. "The crusty old head of the education committee in the legislature said it was so good, he thought maybe that we had elected the wrong member of our family." In a seeming ad-lib, he offers as an aside, "there's something to be said for that."

He tells another story about how Hillary discovered a program in Israel that trains people to be pre-school teachers, "even if they are illiterate," in order to improve pre-K education in poor communities, and help set it up in Arkansas. "Next you know it's in 26 states... there are thousands of people in this country today who have better lives... just because of her. And they no clue, and she didn't care."

Bernie Sanders Voters Were Barely Alive When Bill Clinton Was President

He ends hoping to reach the young voters who have been flocking to Sanders and convincing them that Hillary would serve their interests. "Most of the people in this audience have more tomorrows than yesterdays. Those of us who have more yesterdays than tomorrows, believe it or not, spend most of our time thinking about the future."

But many of the young people in Bernie's base were just born when Bill Clinton was president, so he brings no immediate connection with them, and they are resistant to the argument for pragmatism. This video may prove more resonant with older Democratic who retain nostalgia for the Clinton presidency.
