I found this article, its old, but it relates to objectivity.  Frontline interviewed some top news media editors, columnists, bloggers and advisers to previous presidents.  Its amazing to me that most are eager to say that objectivity does exists.  One editor even noted that objectivity is not a good term because we are humans.  He even went on to object that news media, in part the Washington Post, is biased?  In fact, most people just want to be told what to do.  I wold argue that even though journalists seek to be objective, just like us, they have an opinion.  Just like we hope that judges, teachers, officers and other officials should be objective in any matter at hand does not happen, as everyone brings beliefs, culture and other influences to any problem.  Read the article to see what all the editors, columnist and bloggers had to say about this here:
