Poland holds Presidential election; Donald Trump backs nationalist candidate Karol Nawrock

Poland’s Presidential election has come down to a stark ideological choice: a liberal pro-European mayor versus a staunch nationalist conservative. They are polling so close that the outcome is impossible to predict in the run-off round on Sunday (June 1, 2025).

It’s not just a domestic affair. President Donald Trump has thrown his weight behind the nationalist candidate Karol Nawrocki, and dangled the prospect of closer military ties if Poles choose him over liberal Warsaw Mayor Rafal Trzaskowski.

A contest with global implications

Mr. Trump met with Mr. Nawrocki earlier this month at the White House and sent his Homeland Security Secretary Kristi Noem to a meeting of the conservative pressure group Conservative Political Action Conference (CPAC) in Poland, where she offered a strong endorsement.

Ms. Noem even dangled the prospect of closer U.S.-Polish military ties in the event of a Mr. Nawrocki win, with the implied warning that a Mr. Trzaskowski victory could jeopardise Poland’s security.

At stake is not only Poland’s domestic course but also the international standing of a key European Union and NATO member on the alliance’s eastern flank, in a region gripped by anxiety over Russia’s war in Ukraine.

Sunday’s (June 1, 2025) vote will either empower Prime Minister Donald Tusk, a pro-EU reformer, with a Presidential ally who can advance his rule-of-law agenda — or saddle him with a rival who could veto legislation and block government initiatives.

Mr. Trzaskowski’s supporters argue that a pro-European leader would enhance Poland’s global standing during a time of war in Europe. Mr. Nawrocki’s backers believe only conservative rule can safeguard national sovereignty and traditional Christian values, and they say Mr. Trump’s support would greatly enhance Poland’s security.

Growing support for the populist right

But the candidate who may ultimately decide the outcome is one who won’t appear on the runoff ballot.

Slawomir Mentzen, a 38-year-old far-right politician and beer producer from the central city of Torun, finished third in the first round of voting on May 18, with nearly 15% of the vote. Though eliminated, his supporters — often young, anti-establishment, and deeply sceptical of both Brussels and Poland’s political establishment — have become the most sought-after constituency in the country.

Both remaining candidates have gone out of their way to court Mr. Mentzen and his base. In recent days, each man travelled to the north-central Polish town of Torun, famous for being the birthplace of astronomer Nicolaus Copernicus, to appear on Mr. Mentzen’s YouTube channel, where he has built a following with a mix of libertarian economics, nationalist rhetoric and anti-EU invective.

His influence highlights a broader shift in Polish politics, where the far right — once considered a fringe force — is increasingly shaping the national agenda. It’s also part of a larger trend of hard-right parties gaining traction across Europe.

The appeal of right-wing forces in changing times

Piotr Buras, head of the European Council on Foreign Relations’ Warsaw office, says Poland is part of a larger pattern in which voters turn to populist forces amid rapid social change. But he also cites local factors, such as disillusionment with Mr. Tusk’s coalition.

That coalition, which spans the ideological spectrum, has struggled to agree on key issues, including liberalising the abortion law — a campaign promise. Meanwhile, outgoing conservative President Andrzej Duda has blocked parts of Mr. Tusk’s agenda. Observers say the coalition’s voters must be highly mobilised on Sunday to defeat Mr. Nawrocki.

Many votes in the first round went to protest candidates. Among voters aged 18–29, more than 35% backed Mr. Mentzen, and nearly 20% supported a far-left candidate, Adrian Zandberg, according to exit polls.

In addition, an extreme right-wing antisemite, Grzegorz Braun, won more than 6% of the votes overall.

Mr. Buras believes right-wing protest candidates are more appealing today than those on the left because they promise to restore a lost past, while the left promises a better future that many see as unattainable.

“The world is changing, society is changing very fast, much faster than anytime in the past,” Mr. Buras said, “People are worried and they vote for those who say we can go back to the glorious past.”

Campaigning on a YouTube stage

Since the first round, Mr. Mentzen — co-leader of the Confederation party — has presented both candidates with an eight-point list of demands: no new taxes; defence of cash payments; expanded gun rights; and opposition to NATO membership for Ukraine, among others.

Mr. Nawrocki, who appeared on Mr. Mentzen’s show on June 22, signed on to all eight points — including the controversial Ukraine stance — breaking with his Law and Justice party’s longstanding support for Kyiv’s integration with the West.

Mr. Trzaskowski appeared two days later. He said he could agree with some points, like fiscal restraint, but rejected others. He strongly defended LGBTQ+ rights and reaffirmed that Ukraine should eventually join NATO, once the war ends, calling it key to Poland’s own security.

The YouTube interviews have dominated the political conversation, underscoring how Mr. Mentzen, a TikTok-savvy outsider, has upended traditional campaigning.

The exchange between Mr. Trzaskowski and Mr. Mentzen on Saturday (May 24, 2025) was occasionally tense, especially over LGBTQ+ rights, but remained civil and substantive.

In many ways it overshadowed a traditional televised debate the day before. The substance of that debate did not seem to change the trajectory of the campaign. The thing Poles discussed most was a brief moment when Mr. Nawrocki inserted something into his mouth which he later said was a tobacco pouch. Some have questioned if he is fit to be President if he couldn’t get through a two-hour debate without taking a hit of tobacco.

A post-debate meeting over beer

After the sometimes sharp exchanges, Mr. Mentzen sat down for a beer with Mr. Trzaskowski and others in the pub he owns.

The informal gathering was documented by Foreign Minister Radek Sikorski, who was there as well. He posted a video on social media Saturday (May 24, 2025) evening showing the group with the words: “For a Poland that unites, not divides.”

The video quickly went viral, with commentators speculating about whether it was a spontaneous gesture or a calculated political move. It was also one more example, if more were needed, of how far-right forces in Europe are slowly becoming accepted.

For Mr. Mentzen, the moment was also awkward. The man who made his name skewering the political elite appeared cozy with establishment figures. Critics on the hard right lashed out, revealing fractures in the movement he helped popularise.

After dangling the promises of an endorsement for days, Mr. Mentzen on Wednesday (May 28,2025) afternoon said he wouldn’t offer one to either candidate. “Vote as your conscience tells you,” he told his supporters.
