I can understand not liking Sanchez, although your comment seems too much.
But El Diario, while being biased to the left, has never seemed to me like particularly loyal to PSOE. I used to read El País and I stopped exactly for that reason, but El Diario seems to me like one of the few still doing real journalism.
I love it when I find comments on HN discussing their own countries politics, especially if I don’t know a lot about their country. I hope other readers remember to take your comment, and of course mine, with generous pinches of salt.
