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.
Not a minor issue by any means, absurdly here's a link to the Guardian write up on it.

Given the near-racist tone of some of their other coverage of black crime in London, I put this one in the "oh I don't mean you, I know you, you're fine, it's all the other ones I have a problem with" corner.
I don't think these two things are similar in the way I suspect you believe, other than that they are popular.
I think very little can be gaged from the amount of views something gets on the internet, be it the daily mail or gangnam style.
