The PCE (Partido Comunista de España) has actually a seat in the government coalition but they haven't been communists since the 70s. There are a bunch of other communist parties but you have to sort your way through the patsocs, reactionaries cough Frente Obrero cough, transphobes and revisionists. As in most other imperial core countries, the left is in a very bad state
Totally agree with you, comrade. Thankfully the mods have purged most reactionaries from this site (although they rear their stupid head from time to time)
