The media does not exist to inform you. It exists to get readers and viewers so they can sell advertisng and papers. Telling you dull Gephardt has it made does nothing for ratings or newspaper subscriptions.
Remember that when you look at or read the news. Even when the primaries start they will only give you counts of the Delegates that are won in primary or caucus states. They will not tell you now the party official delegates are pledged to vote. If they did you would know that Hillary has no chance and a brokered convention is very unlikely. You would know the winner a lot sooner than they are prepared to tell you who the winner is. Once you know the nomination winners, you'll quit reading and watching as much... can't have that .. .can they?
