“The biases the media has are much bigger than conservative or liberal. They’re about getting ratings, about making money, about doing stories that are easy to cover.” – Al Franken

And there you have it, folks!  Trying to change your portfolio based on who is saying what in financial news is about as useless as regular women trying to implement Gwyneth Paltrow’s diet and exercise program.
