Hungarian voters have ousted Prime Minister Viktor Orbán after 16 years in power, delivering a stunning rebuke to one of the Western world's most entrenched populist leaders. Why it matters: The political earthquake in Hungary, where Vice President Vance was dispatched to campaign for Orbán in the final days of the election, will ripple far beyond Budapest. State of play: Péter Magyar, a 45-year-old former Fidesz insider who broke with Orbán two years ago and built the upstart Tisza party into a political juggernaut, claimed victory Sunday night. With early results showing a dominant victory, Orbán congratulated Magyar and vowed to continue serving Hungary from the opposition, despite the "painful" defeat.
