I see a meaningful difference between republican and democratic parties. But I myself prefer to draw distinction between conservatism+libertarianism under one quite large umbrella and leftists on another side. I even try to avoid the word liberal in order not to confuse with the classical liberalism.
I see MSM as dominated by leftists with good socialist leaning. I also don't subscribe to the "oligarchy controls everything" idea. Of course, money matter and a lot. But American society has unprecedented vertical mobility, plus the Internet age only increases freedom and helps to expose behind the scene manipulations. So, for the big money present in different organizations' boards, I see it more as their money-making interest, not a conspiracy.
That's okay. The oligarchs prefer it that way - it makes their job much easier.
Mary Mapes is your useful prototype. Career woman, hated Bush so badly her eyes crossed. Took her boss down with her...... will spend her golden years doting on cats and her Bush voodoo doll in a jumbled apartment smelling of cat pee.
