The charismatic extremist is using social and traditional media to blur the lines for voters between racism and disloyalty, intolerance and victimhood.

The ominous billboard on Tel Aviv's Ayalon Freeway calling for expulsions of traitors is the cunning brainchild of Itamar Ben-Gvir, the rising star of the far-Right, who, critics say, is now perhaps the most dangerous politician in Israel.

The head of the Otzma Yehudit (Jewish Power) Party is widely seen as a master at repackaging Israeli racism to gain legitimacy and a significant power base in advance of the November 1 election. Polling pits centrist caretaker prime minister Yair Lapid's bloc of allies against opposition Likud party leader Benjamin Netanyahu's Right, allied with Ben-Gvir’s far-Right camp.

The billboard features pictures of Arab politicians Ahmed Tibi and Ayman Odeh, and calls for their expulsion from the country on the grounds they are disloyal. But it also includes Ofer Kassis, a hard-Left Jewish politician known for his sharp criticism of the army.

"Including a Jewish MK gives Ben-Gvir a way out if someone says he's a racist. He can say, 'Me, a racist? It's people who are not loyal who won't be here anymore,'" says Ori Kol, founder of the left-wing Mehazkim organisation, a digital platform pushing for a democratic and liberal society.

"Ben-Gvir stopped saying 'death to Arabs', he now says ‘death to terrorists'. It's more palatable to many people," Kol, who also heads the anti-fake news portal Fake Reporter, told The Jewish Independent during an interview. "The far-Right has never had such an effective frontman taking his vile ideas to the mainstream."

Kol forecasts a dark future in the event of a Netanyahu-Ben-Gvir victory. "I assume the Israeli legal system won't let an expulsion law get through, but the vibes will change. Things will get more aggressive and more [Arab] people will be killed not only in the West Bank but also within the 1967 borders. We will enter a new era when extreme right-wingers feel they can do so much more."
