True, but they've definitely been spinning things. For one thing, they're incapable of dealing with more than two candidates at a time. Ever notice that it's always two candidates on each side that get the press? They view each election as a prize fight, and that's how the model they use for coverage. So you get two people in the ring for each party, plus a Marlon Brando candidate they cast as #3, and his press coverage boils down to "I coulda been a contender" -- if only he could get in the ring.
The spin on Romney has always been pretty clear. He beat McCain in every state until South Carolina. He lost by five points in Florida (still 2nd place), and yet press coverage afterward was that Romney was "vowing to fight on" -- like he was a desperate man in a lost cause. They've had to spin some races as "must win or else" races for candidates, just to create drama.
Hillary, on the other hand, went months without the press biting on anything negative --, and press criticism of her has been a relatively recent development. I'm not saying they control everything, but I think a significant portion of he country's opinion rides on fad politics.
