Before last weekend, it had been decades since the Spanish parliament had seen such a powerful challenge to the rhetoric of “defending the homeland.” Countering the rising politics of nationalism, Podemos leader Pablo Iglesias told a heated Congress that the real “betrayal” of Spain was “attacking workers’ rights, selling off public housing to vulture funds, and privatizing the welfare state and public services.”

For the far-right forces whom Iglesias was addressing, he and his allies were simply a band of “communists, populists” and regional nationalists run amok. In the view of Spanish-nationalist parties like Vox, the Podemos leader is figurehead of an “anti-Spanish” rabble, entertained by a power-hungry “sociopath” in the form of Prime Minister Pedro Sánchez.

At the heart of this debate was the prospect of a historic coalition agreement between Sánchez’s center-left Socialist Party (PSOE) and Iglesias’s Unidas Podemos — on January 7 sworn in as Spain’s new government. Supported by Catalan and Basque regionalists, along with a mishmash of independents, after years of false starts the two parties are finally forming what they call a “progressive coalition” — for its critics, a “Frankenstein’s government.”
