Not the Communists since that'd disrupt the general image of Europe with Spain. It'd be a pain in the ass to have to explain it too.

I'm sure they could win one turn-over in government by popular demand, if sometime later there's agitation over how inept they're perceived and they're cast out. Another thing to image is that with things like the May 1968 the results of the rioting and the uprising ultimately builds solidarity and support in the then ruling party. It might bring about reforms, but the actual rule hasn't changed.
