Good first post. I can't confirm your percentages from prior knowledge, but I can confirm that you've gotten the leanings of many of these companies right.
My only quarrel is not with you but with conservatives generally, for letting the leftist networks foist these labels of red and blue onto us. Republicans have always been true blue and Democrats have always been marxist red. Why should we let some mogul at ABC/NBC/CBS&Co. reverse the colors on us for propaganda purposes?
The coasts should be red and the heartland blue.
You're so right about that, but those colors have been around too long and are going to stick.
We were deliberately 'smeared' with the RED label. No matter the name, we're going to shove that coveted BLUE label down their collective throats.
