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.
It’s disgustingly easy to be a right wing politician in Europe. You can be a liar, incompetent, corrupt leader but the media will barely punish you. Center-left parties get a lot more flak for much minor things. Not that the center-left is much better, but the media bias is very noticeable.
