Megyn Kelly torched Jack Schlossberg as an “absolute idiot” and “entitled jerk” while mocking the congressional hopeful’s résumé, social media antics and allegedly chaotic campaign during a blistering rant on her podcast Thursday.

The conservative commentator unloaded on Schlossberg — the only grandson of President John F. Kennedy — after the New York Times published a lengthy profile detailing reported dysfunction inside his Democratic congressional campaign.

“Jack Schlossberg, who is perhaps better known as JFK’s grandson … and he’s an absolute idiot,” Kelly said on Thursday’s episode of SiriusXM’s “The Megyn Kelly Show.”

“He’s 33 years old. He is a total idiot.”

Kelly ridiculed Schlossberg’s Ivy League credentials — Yale followed by a joint law and business degree from Harvard — while arguing his career accomplishments failed to justify his congressional ambitions.

“If there’s better proof that those things mean nothing when you’ve got a family connection in particular, I don’t know of it,” Kelly said.

Schlossberg launched his bid last year for New York’s 12th Congressional District, the Manhattan-based House seat being vacated by retiring Rep. Jerry Nadler.

The race immediately drew national attention because of Schlossberg’s family name.

He is the son of Caroline Kennedy and designer Edwin Schlossberg and has long been viewed as the political heir to America’s most famous Democratic dynasty.

Kelly mocked what she portrayed as his lack of meaningful work experience before entering politics.

“The only thing he’s accomplished is he worked for Vogue as a correspondent for like, a couple of freelance articles that went nowhere, and then worked for John Kerry for four months at the State Department doing absolutely nothing,” she said.

“So, that’s it. He’s 33, by this point, you should have something.”

Kelly’s comments came after the Times detailed allegations of campaign turmoil, including missed meetings, staff turnover and erratic behavior.

According to the report discussed on Kelly’s podcast, Schlossberg allegedly skipped strategy meetings, disappeared for stretches of time and once scrapped fundraising calls on launch day because he “needed a nap.”

Kelly sarcastically joked about reports that Schlossberg spends time swimming or paddleboarding in the Hudson River.

“So don’t get too attached to Jack Schlossberg, because he obviously must have contracted some hideous disease,” Kelly said.

“No one swims in the Hudson.”

The podcaster also ripped Schlossberg’s provocative online persona, referencing his history of posting bizarre and explicit content on social media.

“He’s a content creator,” Kelly said mockingly while discussing a debate exchange in which Schlossberg defended his background.

“What public service have you had that would recommend you for this job? He’s a content creator.”

Schlossberg has previously acknowledged that some of his online behavior was intentionally provocative.

Supporters counter that he is reaching younger voters in ways traditional Democrats cannot.

Kelly dismissed that argument outright.

“There are so many kids out there right now in lower- to middle-class communities who are working their asses off with a dream of improving their station in life by getting into one of these Ivy League colleges,” she said.

“And they don’t get to go because this prick, for no reason other than his mom is who she is, and his grandparents were who they were, takes the slot.”

Kelly escalated further by claiming Schlossberg was “very obviously mentally ill” and alleging members of the Kennedy family privately discouraged him from running.

“He’s not just weird,” Kelly said.

“This guy is very obviously mentally ill.”

The Post has sought comment from Schlossberg.

Despite the controversies surrounding the campaign, Schlossberg remains a competitive contender in the crowded Democratic primary.

Federal Election Commission filings through March showed he raised more than $2.2 million.

The latest publicly available poll, conducted in April by Honan Strategy Group, showed Micah Lasher leading the race with 28% support, followed by Schlossberg at 20% and state Assemblyman Alex Bores at 19%.

Attorney George Conway polled at 9%.
