Much as I detest its politics, the Mail is the most visited English-language newspaper site in the world, to be fair.
Daily mail is not bad because of politics but because it's exploitative, sensationalist, devoid of empathy and does absolutely _anything_ to get a click/view/reader. It stands for nothing, there are no standards, nothing is too low and no story too sensitive to bulldoze.
