While social democrats allowed ultra right party Vox to enter the parlament (first time since franco), it is not so bad: the leading right wing party PP probably will not ally with Vox since they both would not have majority. A nice feature of Spanish politics is that they have a party with a percentage of communists (led by Yolanda Diaz), something what would be not possible with ultraconservative countries like Poland.
I understand, that’s a good (and depressing) point, but compared to Poland, at least there is a communist party you can vote for.
