In what universe? The "press" has been unabashedly partisan in the country for as long as I can remembers.
Because like most Sociopaths, the self-proclaimed “smartest people in the room” have a total lack of self-awareness: Trump’s ascension is in a great part due to the HATRED of the MSMedia by decent Americans.
It seemed to me that they became “unabashed” in the 2008 cycle. In 2012, they decided they were proud of it. For 2016, they are trying to be “involved”. They have lost any little credibility they may have ever had and are despised by anyone paying attention.
