Bill Clinton promised voters in 1992 that they'd be getting "two for the price of one" if they elected him to the White House — a presidential duo of the young Arkansas governor and his Yale Law-educated wife.
Nearly a quarter century later, the duo is back — but not quite the same.
As Hillary Clinton fends off a rising challenge from Bernie Sanders, his wife's campaign aides are grappling with how best to deploy what she has described as her "not-so-secret weapon."
Their answer: very, very carefully.
During campaign swings through Iowa and New Hampshire, Bill Clinton treaded fastidiously through tightly controlled campaign events. A natural-born chit-chatter, he was not giving interviews. When he stopped to talk with reporters after one recent event, campaign aides turned up the music, making a conversation all but impossible.
His remarks to voters have been relatively subdued: long on history, statistics and nostalgia. He's dodged questions about Sanders and Republican front-runner Donald Trump, who's been baiting the Clinton family with comments about the former president's past sexual improprieties
"I'm not going there," Bill Clinton said on Wednesday, when asked about Sanders at a campaign event in New Hampshire. "I came here to tell people why I thought Hillary should be president and her ideas are better."
While Bill Clinton remains a popular figure among Democrats, some of the key achievements of his administration form the basis of Sanders' critique against his wife — that she's too willing to compromise liberal ideals for political gain.
The Vermont senator has denounced his rival's policies on trade, same-sex marriage, crime and welfare cuts. He's made reinstating Glass-Stegall, a Depression-era banking law repealed under Bill Clinton's administration, a central attack line of his campaign.
"People don't have a long memory, but Bernie's doing his best to remind them," said Roger Hickey, a co-director of the liberal Campaign for America's Future. "People don't want a recycling of Bill Clinton's presidency. They want somebody who's willing to stand up to the billionaires and corporate power."
Clinton aides say those critiques miss the larger picture of wage growth, job creation and a balanced budget. In a debate last month, Clinton said she would turn to her husband for economic advice.
"He carries a message of peace and prosperity under his presidency and I think a lot of Americans would like to get back to those days," Clinton said in an interview on NBC's "Today Show" on Wednesday.
At an afternoon event in Keene, voters recalled the Clinton presidency fondly, as a time of prosperity.
"The best economic times for my family were when Bill Clinton was president," said Madeline Smeaton, a graduate student in Keene whose father lost her job in the Great Recession. "We were making a lot of money."
Still, some of those economic achievements face a skeptical re-examination within a party that's grown more liberal under the Obama administration.
Bill Clinton has said that he regrets approving the Defense of Marriage Act and the "don't ask, don't tell" policy that banned gays and lesbians from military service. He also has looked back with regret on signing the 1994 crime bill, which led to tougher sentencing for drug offenses.
"I signed a bill that made the problem worse," the former president told an audience at the National Association for the Advancement of Colored People's annual meeting in Philadelphia in July. "And I want to admit it."
On Wednesday in New Hampshire, Bill Clinton detailed the economic growth under his administration, listing statistics on wage growth, the decline in poverty and insurance rates.
He walked voters through Hillary Clinton's policy priorities, stressing the need to invest in infrastructure, renewable energy, small business, college affordability and paid leave. And he sprinkled his remarks with his wife's foreign policy and domestic accomplishments as first lady, New York senator and secretary of state.
"Whatever I say about Hillary's plans, you're entitled to give it a little discount," he said. "But I ought to get some credit for knowing something about how to run the economy."
It's an argument similar to the one he made in 2007, when Hillary Clinton was fending off another insurgent challenger: then-Illinois Sen. Barack Obama. But unlike eight years ago, when his comments about Obama "playing the race card" angered black voters, he made no mention of his wife's primary opponent.
The only veiled criticism of Sanders came Friday in Coralville, Iowa, with a reference to Sanders' support for a single-payer health care system instead of the 2010 federal health care law, also known as Obamacare.
Saying that starting over on health care legislation was not politically viable, Clinton told voters, "We still need to live in the reality-based world."
In New Hampshire, some people said that while Bill Clinton was still a compelling messenger for his wife, they just weren't sold on her quite yet.
"He gave me every confidence that she'd be a great candidate and be a wonderful president," said Steve Taylor, a farmer from Plainfield, New Hampshire. "But Bernie is telling the truth about the economy."
But Reuters reports that Bill Clinton doesn't carry as much influence with voters as he may have in the past.
Bill Clinton simply is not wielding that kind of influence – good or bad – over voters so far this year, according to a Reuters/Ipsos poll. A majority of Americans, including 73 percent of Democrats and 52 percent of Republicans, said Bill Clinton does not factor into their opinion of Hillary for president. ()
The poll, conducted Jan. 7 to 13, found that 12 percent of Americans are more likely to vote for Hillary, the former secretary of state, because of her marriage to Bill. Among Democrats, fewer than half said Bill Clinton should be more prominent in his wife’s campaign, and less than half felt that his presence in the race would boost her chances of winning.
