Germany’s center-right Christian Democratic Union (CDU) declared victory Sunday as exit polls and early results suggest the party garnered the biggest vote share in the country’s elections—and the far-right Alternative for Germany (AfD) is projected to nab a historic number of votes after billionaire Elon Musk ’s endorsement.

The AfD has won new support in western states from voters frustrated by Germany's weak economy, seeking curbs on migration, and fed up with political stasis. It has also attracted younger people, for whom voting far-right does not hold the same stigma as it did for older generations.
