"Editors have always chosen what to print,..."  And you have not noticed the liberal bias of what they chose, but that's convenient for you.  
"Have you not noticed that the DP has a National/International news section before?"  Apparently you are unaware that there is only ONE front page and the Denver Pravda is highly selective as to what they put on that page.  But they of course put out there the liberal stories that fit their views.  Sorry you are so easily manipulated.
