I think most everyone is aware that Hillary represents the deep corruption of the establishment, at least if they care enough to look. It is a bipartisan corruption though, recall that McCain was also deeply involved in arming ISIS, for example. He even went over to have his photo taken with them. Since this level of duplicity isn't a partisan or identity politics issue, MSM isn't really interested in paying it much attention. If the MSM really wanted to blow the lid off of the sordid doings of our elite political class, they could and would have done so years ago.
