I'm not a Macri fanboy by any stretch, so I'm not defending him... but that web site — "Política Argentina" — leans towards the left. Obviously, they will report all news through an anti-Macri lens.
It's hilarious when people bitch about Clarín or La Nación being biased... and then go and deem everything in Pagina12 or any other pro-K newspaper is the absolute truth.
Sorry, but just because you agree with the political position of a certain newspaper doesn't mean it isn't written to pander to the political leanings of their readership. Unbiased news hasn't existed for a long time (maybe ever). But people in general tend to go out and seek information that confirms their existing beliefs. The internet just made things easier.
(Not to mention that no one should be shocked when politicians from the opposing party claim Cambiemos is doing bad things. Maybe they're right. Maybe Vidal is helping create an electricity monopoly. I don't know. But of course they'll spin everything to make him look bad no matter what the truth is. That's how politics works.)
