Rep. Alexandria Ocasio-Cortez has a very busy schedule of talking about herself on social media, on TV shows and podcasts and tin cans. She flits from conference to conference, proposes to abolish cows and planes, and her actual constituents are left in the dark.

The main function of an elected official is to serve their constituents. As bad as Rep. Crowley was, it’s hard to believe he could have done any worse than Cortez is doing. 

The Westchester “Girl from the Bronx” only uses the place as the backdrop for narcissistic media coverage.

Ocasio-Cortez was in New York City last weekend and this weekend, with appearances in Queens on both Saturdays — yet she was not seen coming or going from her Parkchester pad either day.

Her apartment’s next-door neighbor said she had never seen Ocasio-Cortez. Another neighbor, who has lived down the hall from the congresswoman’s apartment for the last 40 years, said he’d never seen her or her boyfriend, Riley Roberts, who has claimed the address as his own since last spring.

“I would have remembered,” said the neighbor when shown a photograph of Ocasio-Cortez.

Workers at Jerry’s Pizzeria, less than a block from her building, and at the local grocery store said she had never patronized their businesses — and a server at a nearby taqueria said the congresswoman had only come in to be filmed by news crews.

A postal worker who delivers mail to the building said that in the last 10 years he has only seen Ocasio-Cortez intermittently, and that several months’ worth of mail regularly accumulates in the mailbox before anyone bothers to collect it. The worker said that Ocasio-Cortez and Roberts were the only ones getting mail at the address.

“Just because their names are on the box doesn’t mean they live there,” he said.

And in 2017, when Ocasio-Cortez first filed paperwork to become a congressional candidate, she didn’t even know what district she lived in, mistakenly declaring plans to run for neighboring District 15 before correcting the error days later.

Of course. Socialist carpetbaggers find areas they can exploit, but they don’t actually want to live there.

Meanwhile her constituents are left high and dry.

Ocasio-Cortez has made four trips to the city since she was inducted to Congress on Jan. 3, according to a Post review of published reports and social media. Those excursions featured five public events in her district — and three high-profile Manhattan appearances, including a Jan. 21 guest slot on “The Late Show with Stephen Colbert.”

The space slated for Ocasio-Cortez’s constituent office is in a new building in Jackson Heights.

Suites in the building at 74-09 37th Avenue rent for about $40 per square foot. Ocasio-Cortez’s office, on the third floor, is just under 5,000 square feet, which would bring the annual undiscounted rental price to $200,000 or nearly $17,000 a month.

When The Post visited last week, the congresswoman’s office was still under construction, with workers building interior walls and installing drywall. A carpenter there said the work would probably take several more weeks to complete. A staffer said at a community board meeting that it would open March 4.

In the absence of a district office, and with no way to contact the rookie congresswoman, voters have resorted to desperate measures.

“Constituents come here and leave notes on the door,” said the postal worker at her Parkchester apartment building last weekend. “But it’s a waste of time.”

And once the office does open, its only function will be promoting Cortez. Not helping her constituents.

They’ve gone from one absentee lefty Dem to another.
