Obama's approval rating is near its highest point ever — and that could be a big problem for Donald Trump

Barack Obama is prepared to campaign for his party's likely nominee more than any sitting president in recent history — starting next week in Charlotte, North Carolina.

That could be a big problem for the GOP. And a huge boon for Hillary Clinton, the presumptive Democratic nominee.

"I'm fired up," Obama said in a video endorsing Clinton last month.

And, apparently, he's ready to go. In a newly released Washington Post/ABC News poll, Obama's approval rating hit 56% — his highest level since 2011, after the killing of Osama bin Laden.

Last month, an NBC/Wall Street Journal poll found that President Barack Obama's approval rating had jumped to 51% — its highest point since his second inauguration.

NBC's team of political analysts called it the "most important number" out of the poll.

"Why is it important? Because it means that Obama will be an asset to Hillary Clinton on the campaign trail unlike he was in the 2014 midterms, when his approval rating was in the low 40s," NBC's Chuck Todd, Mark Murray, and Carrie Dann wrote.

The number might seem arbitrary. But historical precedent suggests it could bode well for Clinton, Obama's former secretary of state.

Early this year, Obama's approval rating hit 50% in the weekly average from Gallup's daily survey. Almost three months later, his number in Gallup's poll stands at 51%, as of Friday. For Obama, whose approval ratings have been stuck in the mid- to low-40% range for much of his second term, it was a notable bump.

"While it's hard to pinpoint precisely why Obama's approval rating has risen among Democrats recently, there are a number of plausible explanations," wrote Andrew Dugan, a Gallup analyst, and Frank Newport, the organization's editor-in-chief, in a post earlier this year.

One of the explanations, the pair concurred, was that "the unusual status of the Republican primary race — exemplified in particular by frontrunner Donald Trump's campaign style and rhetoric — may serve to make Obama look statesmanlike in comparison."

Trump has come into Obama's crosshairs recently. And with good reason: More so than at any other presidential hand-off in recent history, so many elements of the current administration's legacy are at stake.

The presumptive Republican nominee has pledged to undo signature achievements on healthcare (the Affordable Care Act), the environment (historic new regulations aimed at curbing climate change), and foreign policy (the Iran nuclear deal).
