Comedian Volodymyr Zelensky’s dramatic lead in exit polls Sunday — in many of them he received more than 73 percent of the vote — was so overwhelming that it prompted a concession of defeat by incumbent Petro Poroshenko even before the official results were in, Radio Liberty reported.

If Zelensky is sworn in as president, his prime minister — at least for a while and possibly until the parliamentary elections scheduled to take place sometime later this year — will be Volodymyr Groysman, a Jewish politician who was the mayor of the city of Vinnytsia.

To some of Proshenko’s critics, the landslide success of the vague campaign by the politically inexperienced Zelensky was not surprising in light of widespread resentment over the persistence of corruption under Poroshenko, who was elected in 2014 on a platform that vowed remedial action on exactly that front.

More unusual to some, however, was how Zelensky’s appears to have won the elections so decisively in spite of how his Jewish ancestry – his mother, Rima, is Jewish and he has jokingly referred to this during the campaign — is well known in Ukraine.

After all, Russia and other critics claim Ukrainian society has a serious anti-Semitism problem and legacy.

“Imagine, a pure-blooded Jew with the appearance of a Sholom Aleichem protagonist wins by a landslide in a country where the glorification of Nazi criminals is enacted into law,” wrote Avigdor Eskin, a Russian-Israeli columnist, in an analysis published earlier this month by the Regnum news agency.

Eskin in column on Zelensky downplayed allegations of widespread anti-Semitism in Ukraine, attributing much of the attention to the problem in media and beyond to propaganda by Russia, which is involved in an armed conflict over territory with Ukraine.

But Eskin’s statement about Ukrainian laws glorifying Nazi criminals is not inaccurate, and Russia is not alone in criticizing Ukraine over this and other issues connected to anti-Semitism.

Last year, Israel’s government singled out Ukraine as a regional trouble spot in the Israeli government’s annual report on anti-Semitism.

“A striking exception in the trend of decrease in anti-Semitic incidents in Eastern Europe was Ukraine, where the number of recorded anti-Semitic attacks was doubled from last year and surpassed the tally for all the incidents reported throughout the entire region combined,” the report said. The authors of the report counted more than 130 reported anti-Semitic incidents in Ukraine in 2017, they said.

Also last year, more than 50 U.S. Congress members condemned Ukrainian legislation that they said “glorifies Nazi collaborators” and therefore goes even further than Poland’s controversial laws limiting what can be said about local complicity during the Holocaust.

A letter signed by the U.S. lawmakers  stated, “It’s particularly troubling that much of the Nazi glorification in Ukraine is government-supported.” It noted ceremonies, gestures and legislation venerating leaders of the UPA and OUN militias, who fought alongside Nazi Germany during World War II and whose troops participated in atrocities against Jews and other victims.

Poroshenko’s government greatly encouraged glorification of those troops and leaders as fighters for Ukrainian freedom who it insisted sided with Germany only in order to fight against the Russian-controlled Soviet Union.

Several cities across Ukraine named streets for the Nazi-collaborator Stepan Bandera, who prior to Poroshenko’s time in office was openly glorified only in the country’s west.

Meanwhile, in the western city of Lviv, nationalists became emboldened enough to celebrate with city authorities’ permission the anniversary of the 14th Galician division of the Waffen SS. The anniversary events featured men parading in Nazi SS uniforms on the street.

Such sights would have been unthinkable under Viktor Yanukovych, the corrupt president who was deposed in a 2013 revolution that ended with Poroshenko’s election. Careful to alienate neither ethnic Russians in Ukraine nor its powerful neighbor to the east, Yanukovych was less tolerant of this nationalist phenomenon.

Om this subject, Zelensky has said only that he personally does not favor the veneration of people like Bandera, whom he described as “a hero to some Ukrainians.” It was a markedly reserved formulation compared to the unreserved endorsement of figures like Bandera by officials under Poroshenko.

The presidential campaign itself has featured some anti-Semitism.

In some far-right circles, Zelensky’s work in a television stationed owned by the Jewish billionaire Igor Kolomoisky was proof of his belonging to a “Jewish cabal.” But it made Zelensky popular with other nationalists who appreciated Kolomoisky’s reputation as a fiery patriot.

Alexander Paliy, an influential political analyst supporting Poroshenko, last month stirred controversy when he wrote on Facebook that, despite his “respect” for Jews and some Russians, “The president of Ukraine should be Ukrainian and Christian, like the absolute majority of Ukrainians.”

Such rhetoric is shocking to many of Ukraine’s 300,000-odd Jews, whose ancestors suffered murderous anti-Semitism in Ukraine for centuries before, during and decades after the Holocaust.

The French-Jewish philosopher Bernard-Henri Lévy also referenced Ukrainian Jew’s bloody history in an interview with Zelensky, the 41-year-old son of scientists who lived near major Soviet army bases in Ukraine, that he published earlier this month in the Le Point weekly.

“His Judaism. It’s extraordinary that the possible future president of the country of the Shoah by Bullets and Babi Yar is a self-affirmed Jew from a family of survivors from Kryvy Rih near Dnipro – the land of pogrom if ever there was one,” Levy wrote. “This postmodern kid, is he new proof that the virus of anti-Semitism has been contained” after the revolution, Levy added.

Not denying his Jewish ancestry, Zelensky declined to explore it at length in the interview, Levy wrote. On this subject, he replied with typical self-deprecating humor, telling Levy: “The fact that I am Jewish barely makes 20 in my long list of faults.”

Zelensky, whose mother, Rima, is Jewish, has ingratiated himself with the Ukrainian public with such jokes as the star of “Servant of the People” – a primetime television show where he portrays a teacher thrust by an unlikely chain of events to become Ukraine’s president. He announced his candidacy in January, becoming an instant favorite.

This popularity has allowed Zelensky to both win on an unusually vague platform and distinguish himself from his professional politician rivals, with their proclivity to hyperbole and nationalist slogans.

For example, when a reporter asked him how he would deal with Russian President Vladimir Putin, Zelensky reverted to his comic roots, saying “I would speak to him at eye level.” It was a reference to him and Putin being at least three inches shorter than Poroshenko, a 6-footer.

Zelensky opaqueness means a high level of uncertainty, Dolinsky, the Jewish community leader, said.

“We will need to wait and see what kind of president Zelensky turns out to be,” said Dolinsky, who was an outspoken critic of some policies of the Poroshenko administration. “What is clear is that Poroshenko’s attempt to appeal to nationalism has failed. Ukrainians said they wanted chance. And I am feeling optimistic.”
