Former President Barack Obama returned to the campaign trail on Thursday, visiting New Jersey to stump for Democratic governor candidate Phil Murphy.
NEWARK -- Making his first campaign appearance since leaving office in January, former President Barack Obama implored a packed ballroom in Newark on Thursday to help reject "the politics of division" gripping America by electing Phil Murphy, the Democratic nominee for New Jersey governor.
In a 20-minute speech at the Robert Treat Hotel, Obama said the world will have its eyes on New Jersey when voters pick a successor to outgoing Republican governor Chris Christie on Nov. 7.
"The world counts on American having its act together," Obama told the crowd at the Robert Treat Hotel. "The world is looking at us as an example."
"In 19 days, the world is going to be looking at New Jersey," he continued. "In 19 days, the world is going to look and see what kind of politics we believe in."
Obama, a Democrat, never mentioned his Republican successor, President Donald Trump, by name. Nor did he specifically mention any of the controversies that have surrounded Trump's first nine months in office.
But Obama said "what we can't have is the same old politics of division that we have seen so many times before, that dates back centuries."
"We thought we put that to bed," Obama said. "That's folks looking 50 years back. It's the 21st century, not the 19th century."
He cast the New Jersey race -- in which Murphy's Republican opponent is Kim Gaudango, Christie's lieutenant governor -- as a place to begin healing.
New Jersey is one of only two in the nation to hold a governor's race this year, along with Virginia. After the Murphy event, Obama sped off for Virginia to campaign with Ralph Northam, the Democratic candidate in that state.
"Phil Murphy understands that New Jersey wants to move forward," Obama said in Newark. "It doesn't want to move backwards."
Obama noted that he has known Murphy, a former Goldman Sachs banking executive and top Democratic fundraiser, for years. In 2009, Obama picked him to become U.S ambassador to Germany, a position Murphy held until 2013.
Obama said Murphy told him a few years ago during a visit to the White House that he was thinking of running for governor.
"I wasn't surprised because I knew him and (his wife) Tammy and I knew their character," Obama said. "I knew how much they love their great state and how much they want to give back."
Murphy was joined Thursday by a parade of top Democrats -- including U.S. Reps. Donald Norcross, Frank Pallone, and Donald Payne Jr. -- who lamented Obama's absence from the Oval office.
"We don't just miss him as Democrats," Murphy told the crowd. "We miss him as Americans."
New Jersey is a heavily blue state, and Trump's approval rating among voters here sits in the 30s. Meanwhile, an August NBC News/Wall Street Journal poll showed 51 percent of Americans have a favorable opinion of Obama.
Thursday's crowd -- which Murphy's campaign said was larger than 1,000 and was open only to people who were invited or volunteered for the campaign -- yelled wildly as Obama took the stage.
"Four more years!" they chanted.
"I will refer you both to the Constitution as well as to Michelle Obama to explain why that will not happen," Obama told them.
It was the first time Obama campaigned for a gubernatorial candidate in New Jersey since 2009, when he stumped for then-Gov. Jon Corzine. The Democrat lost his re-election bid to Christie that year.
At her own event Thursday, Guadagno -- who is trailing Murphy by double digits in all polls -- dismissed Obama's list, noting that it "didn't work" for Corzine eight years ago, "and it will not work today."
Obama implored Murphy suporters to help get out the vote, saying you "can't take this election -- or any election -- for granted."
"I don't know if y'all noticed that," he said in a sly reference to Trump's upset over Democrat Hillary Clinton last year.
Obama is the latest in a string of big-name Democrats to visit New Jersey in recent weeks to campaign for Murphy, joining former U.S. Secretary of State John Kerry and former vice presidents Joe Biden and Al Gore.
Clinton, the former U.S. secretary of state under Obama, will appear at a fundraiser for Murphy in Harrison on Sunday.
