I admire Alexandria Ocasio-Cortez, who at 29 became the youngest woman ever elected to Congress. She has spoken truth to power — by seizing it. Like AOC, I’m also a Bernie Sanders-voting socialist, which means that I support her efforts to push the Democrats to the populist left, where they belong.

But even I have had it with her nonstop Twitter antics and hype-generating stunts. The latest came Friday, when she released a video of herself dancing in the halls of Congress. That came in response to footage that surfaced online of AOC dancing in similar fashion when she was in college.

“I hear the GOP thinks women dancing are scandalous,” she wrote. “Wait till they find out Congresswomen dance too!” The post had garnered more than 74,000 retweets as of this writing — and done exactly nothing to advance democratic socialism in America.

Compare AOC with Sanders. The Vermont socialist worked doggedly to shift Democrats toward economic populism, not least by having the $15 minimum wage ­adopted in the party’s platform. He snatched victory from electoral defeat.

AOC must emulate her elder in another fashion: getting to work.

By the time America was “Feelin’ the Bern,” Sanders had been a US representative for 16 years and a senator for a decade. AOC’s ­résumé? Primarying Joe Crowley, an out-of-touch white congressman in one of the nation’s most ethnically diverse districts.

Let’s stop acting like AOC was David to Crowley’s Goliath. She beat a stale opponent in a district where she shared Hispanic heritage with nearly half the constituents. The attention she has ­received since then is nothing short of ridiculous.

Since becoming her party’s biggest star not named Beto, AOC has made daily headlines for ­doing nothing. The media swooned when she decided to take a “self-care” break, with The Washingtonian magazine even recommending the perfect cocktail for her time off. The Huffington Post, meanwhile, boldly reported on the intricacies of hanging her office plaque. What a scoop.

AOC has ceaselessly fed this fawning coverage, turning a social-justice movement into a one-woman show. Political stunts like storming Nancy Pelosi’s office did more to help her than her climate-change cause, and Twitter feuds against everyone from Lindsey Graham to Sarah Palin to Politico accomplish nothing more than rile up her young, social-media-savvy base.

Some Dems have seen enough. Most recently, outgoing Sen. Claire McCaskill labeled AOC a “shiny new object.” Lost in her poor choice of words was a sound warning: “I hope she realizes that the parts of the country that are rejecting the Democratic Party, like a whole lot of white working-class voters, need to hear about how their work is going to be respected . . . and how we can stick to issues that we can actually accomplish something on.”

As AOC takes her seat in the House, lawmakers face an emergency: a partial government shutdown that hampers several government departments and leaves some 800,000 federal workers furloughed or working without pay. Burdensome debt, crumbling infrastructure and a still-disillusioned working class are other problems in need of bipartisan solutions.

Given Congress’ recent track record, progress will be slow, frustrating and difficult. What the process doesn’t need is an attention-hungry rookie representative hindering compromise with demands that, while perhaps noble, are unrealistic given the political landscape.

Her fans in liberal-media silos adore her every proclamation and feed her celebrity. But once her pie-in-the-sky agenda meets legislative reality, her young base will have a cold awakening, furthering the millennial malaise that continues to cost Democrats elections.

Don’t get me wrong: Like AOC, I believe the federal minimum wage should be raised to $15. I believe in Medicare for all. And I believe public colleges should be tuition-free.

But believing and knowing are two different things. And what I know is that these policies simply aren’t politically feasible in the current environment. That doesn’t mean the left should abandon these ideals. But it does mean we should accept, and not railroad, achievable, incremental measures in the meantime.

We need less rock star and more rock steady. It’s time for AOC to delete her Twitter app — and get to work.
