President Obama’s Quiet Case for Hillary Clinton in 2016

— -- In her final days as secretary of state, Hillary Clinton said goodbye to President Obama over a lunch of fish tacos in the dining room off the Oval Office. As a parting gift, she gave her former rival 20 pages of recommendations for what to do in his second term.

“Tearing up, I hugged the president and told him again how much our work and friendship meant to me,” Clinton writes of Obama in the new epilogue of her book “Hard Choices.” “And that I'd be on call if he ever needed me.”

As the 2016 presidential campaign kicks into gear, Obama needs Clinton more than ever before – a message he’s made increasingly clear over the past two years, without having to pick up the phone.

Obama has heaped more effusive praise on his former secretary of state than just about any other high-profile Democrat, including his own vice president, Joe Biden, who has also aspired to the nation’s top office.

Obama has declared Clinton “a world figure” and an “extraordinary talent.” He said in a joint interview with “60 Minutes” that she was “one of the most important advisers” he’s had, and a “strong friend.”

“If she’s her wonderful self, I’m sure she is going to do great” in the campaign, Obama said in an interview this week.

The accolades and encouragement are a far cry from the lukewarm “likable enough” description Obama affixed to Clinton during a 2007 primary debate. White House officials told ABC News that the president “thinks very highly” of Clinton as a candidate and that she has a “strong case to make” to become his successor.

To be sure, President Obama remains coy about an explicit primary endorsement and, officials say, will likely keep a low profile in the early stages of the campaign. He told CBS News in an April 2014 interview that Biden would also be a strong candidate as “one of the finest vice presidents in history.”

“I don’t necessarily want to jam them up,” Obama said of his potential involvement with the candidates in the early Democratic field.

Still, as Clinton formally launches her second presidential bid this weekend as the dominant Democratic front-runner, Obama is quietly banking on her to be the defender of his legacy.

He’s cited her discipline, stamina, thoughtfulness and “ability to project” their shared values as factors that make her “extraordinary” in his eyes.

On Twitter, Clinton has given an unabashed embrace of her former boss’s policies, defending Obamacare and his immigration executive action. She’s also defended the administration’s sweeping reforms of the financial system and the president’s economic blueprint outlined in his State of the Union.

Ties to the Obama White House already run deep. The Clinton campaign apparatus is stuffed with former top Obama administration policy makers and strategists, including former White House communications director Jennifer Palmieri, former Obama senior counselor John Podesta, and former Michelle Obama aide Kristina Schake.

Administration officials deny any planned direct coordination between the Obama White House and the Clinton campaign on messaging or legislative agenda, but do not rule it out.

“I’m confident that there will be a lot of agreement between the priorities that she articulates and the kinds of priorities this president has been fighting for the last six years,” said spokesman Josh Earnest late last month.
