Bardella’s teenage messages, and a campaign already at war

France’s presidential campaign is no longer warming up. A Toluna–Harris Interactive poll published this week put Marine Le Pen at 35–36 percent in the first round of the April 2027 vote and winning a runoff against both Édouard Philippe and Jean-Luc Mélenchon. Jordan Bardella, 31, president of the National Rally (RN), is her designated prime minister. That is the setting in which Mediapart, on Monday, published what it described as a months-long investigation into private messages it attributes to Bardella between 2013 and 2015 — antisemitic and conspiratorial remarks from the years when he was a teenage activist in the old National Front.

The lines Mediapart quotes are unambiguous if they are his. One message says “all the banks are owned by Jews.” Another: “The Jew must dominate other peoples, crush them and rob them; a Zionist is necessarily a Jew, and fundamentally so.” A third imagines a “New World Order dominated by Israel, with Jerusalem as its capital.” Pierre Moscovici, then economy minister, is alleged to have been accused of wanting to “save companies” in order to “avenge Moses.”

Mediapart says the corpus runs to dozens of written conversations, independently authenticated, and is backed by testimony from former party colleagues identified only by first name and an initial. It has not published screenshots. Co-author Antton Rouget said on Tuesday that if the paper’s methods continued to be attacked, “we will authenticate and we will publish the documents.” Fabrice Arfi, who leads Mediapart’s investigations, said the outlet was “200 percent sure” of what it had printed and could demonstrate it “in public debate and before the courts.”

Bardella’s reply was equally categorical. He called the texts “crude forgeries,” said they attributed to him “deranged and antisemitic remarks that I supposedly made when I was a minor,” and instructed his lawyers to sue for defamation and, he later added, forgery. On CNews he spoke of “the beginnings of a total war” to destabilise the campaign. Le Pen stood beside him in parliament on Tuesday and said she had “absolute confidence” in him; on Monday she had already called the report “a fake, a manipulation, a dirty trick.”

The calendar is doing political work

Bardella was born on 13 September 1995. He turned 18 in September 2013. Mediapart’s window is 2013–2015. Some of the quoted exchanges are placed in the summer of 2013, when he was 17; others, if dated after his birthday or in 2014–15, would have been written by an adult who was already rising inside the party — departmental secretary in Seine-Saint-Denis in July 2014, regional councillor in December 2015.

The “he was a child” defence therefore covers only part of the alleged corpus, and only if the dating holds. It does not answer the harder question of why a report that Mediapart says took months appears now, seven months before the first round, rather than in 2024 when Bardella led the legislative list, or in 2022, or when he first became the public face of dédiabolisation.

There is a non-conspiratorial explanation: investigations end when sources talk and lawyers sign off. There is also a campaign explanation, which Bardella is selling hard: that the file was held for the moment when Le Pen was cleared to run and he was locked in as her premier. Both can be true; neither is proven. What is already true is the noise. Opponents have called on him to resign. The RN has answered with a standing ovation.

How such claims can, and cannot, be substantiated

Private chats from a decade ago are difficult evidence. Metadata, original files, recipient testimony and linguistic quirks (Mediapart reproduced spelling mistakes) can strengthen a case. Screenshots alone can be forged. Mediapart has staked its reputation on authentication it has not yet shown the public. Bardella says the paper refused to let his lawyer see the documents. A libel trial, if it proceeds at speed, will force a choice: produce the raw material or retreat. Until then, France is being asked to treat either a newsroom or a probable future prime minister as the fabricator.

If the messages are genuine, they collide with the RN’s central project since 2011: to bury Jean-Marie Le Pen’s antisemitism, court Jewish voters, and present Bardella — who visited Israel in 2025 at the government’s invitation — as proof that the party has changed.

Yonathan Arfi, president of the Crif (Representative association of the Jewish organisations in France), said that if the elements made public are confirmed, the statements by the young Bardella represent a stinging rebuttal of the National Rally’s strategy of de-demonisation.

Political scientist Patrick Lehingue, co-author of a book on the FN-to-RN transition, told the catholic outlet La Croix that such writings looked “entirely plausible” in the Front National of that period: de-demonisation was only beginning, respectable candidates were put forward in public, but “antisemitic and homophobic black sheep popped up everywhere,” and such talk was “a sign of internal complicity.”

Dominique de Villepin struck a more cautious note: the affair “must give rise neither to a gratuitous trial of intent nor to personal exploitation,” but de-demonisation “cannot be a communications operation.” De Villepin himself is a candidate for President, although his chances are slim.

Two electorates, two reflexes

No poll yet measures the hit. The likely split is familiar. Voters already intending to back Le Pen have spent years treating Mediapart as hostile and “affairs” as the price of approaching power. For them, Bardella’s line – that attacking him is attacking “millions of French people” – is a loyalty test, not a fact-check.

The other bloc, the one that will vote for whoever can stop Le Pen, does not need a court judgment. The allegation itself restates what they already believe about the RN’s core. Between those poles sits a narrower group: voters who accepted Bardella as the sanitized product and may now ask whether the sheen was only ever a coat of paint.

That is why the timing argument cuts both ways. Late publication looks like a campaign weapon. Early silence, if the material is real, looks like a missed public interest. Either way, an unproven file can still do the work of a proven one: it occupies the news, forces the RN onto the defensive, and reminds a country heading into a Le Pen–Bardella presidency that the party’s oldest stain is not a matter of ancient history.
