The Washington Media Consensus against Trump

I see now the tweets by mainstream journalists: all are in agreement on Trump.  I saw the other day one New York Times correspondents warning about the dangers of Trump.  I don't get that: 8 years of Bush and 8 years of Obama, and those same people never saw dangers of their policies, but after one month of Trump they see danger?  This is not in defense of Trump but in opposition to the media biased consensus forming.
