Hungary's Viktor Orban is facing the toughest test of his political career: the parliamentary election in Hungary on April 12. Orban's poll numbers have trailed those of the opposition Tisza party for months.

During the campaign, Orban has been leaning for support on his international allies. From Argentina's libertarian President Javier Milei to France's Marine Le Pen, right-wing figures across the globehave rallied behind Europe's longest-serving leader.

Now US Vice President JD Vance is expected in Budapest, just days before the vote. Can Orban's far-right friends tip the balance?
