So Sumar’s (Spanish party) politicians will apparently be distributed across both The Left and the Greens European parties. Presumably an image maneuver, since joining an European party usually doesn’t bind your vote, and Spanish green parties usually get integrated in leftist electoral options anyway.
Yeah, if you ask Hungary, one party is enough, they can manufacture your consent and tell you what your opinions are just fine.
Two party systems are just for hippies who want to believe they can change anything important while they get a show of tug of war on issues no politician really cares about.
