Where in the world does Alexandria Ocasio-Cortez live?

She has no district office and no local phone number, unlike the state’s three other freshman members.

It’s unclear if the 29-year-old lawmaker, who represents the Bronx and Queens, actually lives in the Parkchester neighborhood that has been so closely tied to her rise — even though she won her upset victory over fellow Democrat Rep. Joe Crowley with accusations that his home in Virginia made him too “Washington-focused” to serve his district.

Ocasio-Cortez used her deceased father’s Bronx condo on her voter registration since 2012, and even posed in the one-bedroom Bronx flat for celebrity photographer Annie Leibovitz in a Vogue magazine profile after her stunning November election. But The New York Post could find little indication she lives there.

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

A district office “makes government immediately responsible and accountable to the citizens,” said Jadan Horyn of Reclaim New York, a government watchdog group. “Constituents need to know their representatives are working for them, and not for national prominence.”

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 the Parkchester apartment building last weekend. “But it’s a waste of time.”

Meanwhile, in Washington D.C., Ocasio-Cortez has rented a pad in a luxe building in the chic Navy Yard neighborhood, where studios start at $1,840 a month, according to the Washington Examiner.

Her new digs feature gold-plated amenities like a rooftop infinity pool, a cycling studio with a dozen pricey Pelotons, men’s and women’s saunas, and a golf simulation lounge — but no affordable units for low-income residents, in spite of a local law that requires them, the news site reported. Liberals say it doesn’t matter and quickly change the subject to a wide array of other topics.

So apparently she lives in Washington, DC. Some life, she goes from $7,000 in her bank account to $200,000, but her supporters say she is working hard for the money.

A bartender who is virtually illiterate who calls herself “democratic socialist”, making all that money…what a fishy world.
