Real "Investigative Journalist" in the style of Woodward & Bernstein appear to be a thing of the past and seem to focus on writing books only. I believe the media employees a few who write an initial copy of a story, than the crowd of staff writers block copy it into a dozen different articles to blanket a story into days with short burst articles and talking head news time slots that are measured in seconds. As a result we the public never get a full in-depth story presented to us, we get a series of sound bytes and a dozen different articles, none of them containing enough real facts for an informed decision, but enough to make a "shoot from the hip" judgement.
The real problem is we now have people in our government that make spur of the moment decisions based upon this low quality "reporting" for their own personal political advantage and not for doing the work of the people.
Personally, I try to stay with news sources that at least try to add some meat to their reporting and if I see a candidate relying on twitter to communicate their views and I run.
