"Unless they are on the editorial pages, journalists are supposed to maintain an unbiased, apolitical stance so as to report without prejudice. Of course, that is the optimum and hardly ever happens any more"

Since when have Keith Olberman, Rachel Maddow, Ed Schultz, etc., been calling themselves "journalists?" They are commentators, just as are Bill O'Reilly, Sean Hannity, etc. Only Keith, Rachel, Ed, etc. don't claim to be "fair and balanced." I think they are - or at least Rachel is - MORE fair and balanced than Hannity, Beck, O'Reilly, etc., but they don't claim to be objective, impartial news reporters.
