No, really, my progressive agenda kills ’em in Des Moines.

Mayor de Blasio says the people who know him best — New Yorkers — don’t appreciate his first-year accomplishments nearly as much as folks in the rest of the US do.

In a seven-page profile published in Rolling Stone magazine Wednesday, Hizzoner suggested his big-ticket items like the expansion of pre-K get drowned out by coverage of the day-to-day headaches that come with running a city.

“A lot of people outside New York City understand what happened in the first year of New York City better than the people in New York City,” he told the magazine.

“But I’m convinced something very special happened here.”

His self-aggrandizing assessment came a day after a Wall Street Journal/NBC 4/Marist College poll found that 49 percent of New York voters think the city is headed in the wrong direction, while 45 percent say it’s not.

Last month, the mayor traveled to Nebraska, Iowa and Wisconsin as part of a tour touting his progressive agenda, which includes a higher minimum wage — and yet 67 percent of Iowans polled at the time didn’t know enough about him to state an opinion.

De Blasio shellacked his predecessors in the Rolling Stone piece.

The mayor scoffed at a popular narrative that former Mayor Michael Bloomberg was so rich, he couldn’t possibly be in anyone’s pocket.

“Part of that was hype because he still had favorites and a clear free-market worldview,” de Blasio said.

“I mean, for God’s sake, when there was a critical op-ed in The New York Times about Goldman Sachs, he went to Goldman and gave a pep talk to the employees! When a struggling school was having troubles in East New York, he didn’t go there and give a pep talk.”

He also dismissed the notion that former Mayor Rudy Giuliani deserves the bulk of the credit for restoring order and safety to the city — even though Giuliani’s first NYPD commissioner is also de Blasio’s top cop, Bill Bratton.

“I agree that he was good at selling himself, and a lot of media over-accepted his version of the story,” de Blasio said of Giuliani. “So, yeah, do you give him credit for figuring out a way to get more credit than he deserves? Sure, if that’s credit.”

The mayor resumes his out-of-town excursions on Tuesday, heading to Washington, DC, where he’s set to unveil a 13-point, left-leaning “Contract with America” alongside Massachusetts Sen. Elizabeth Warren and others.
