I normally don't write much for the benefit of the Republican party as such, or for conservatives as opposed to reactionaries for that matter. In general, I view conservatives as potential, or perhaps latent reactionaries and want to help them achieve their reactionary destiny.
But today, I'll write something of direct partisan interest to Republicans. Here's the fix you're in. You have a bunch of networks around the 5th-15th percentile of Leftism relative to the American population. You have one network right around the 50th percentile. Even your 'extreme' talk radio types are at most 60th-65th percentile. Ask yourself this;
Does this not appear to be a recipe for fairly rapid movement Leftward of the universe of acceptable discourse? The Overton window if you like that term?
If you had any sense, you would, probably instead of dumping money on yet another NCAA college football team, establish a news network that is far to the right of you. I suggest around 95th percentile---as far Not-Left as the most biased major networks are Left. This will make you seem much less extreme. It will make Fox seem 'balanced'. It will also give you the ability to have neutral or friendly moderators in debates. In addition, it will give top cover for your guys who make 'gaffes' (read, who say truths imperfectly that most people actually believe in). It is even better if said network criticizes you from the not-Left extensively, as it will not be seen as your house organ. There are tons of things in our culture that have 20%, 30%---and even near majority support that are considered unspeakable in the mainstream media.
As to how to get there, well, if you've got the money, I suggest a campaign of terror in the media spectrum auctions. Even if you don't win initially, you can bleed them of money by ratcheting up the prices they have to pay for access to their spectrum. If you do win, you can exploit their advantage of incumbency at their position on the frequency dial.
Aren't you tired yet of having your positions of 10 years ago denounced as retrograde and atavistic by YOUR OWN PARTY?
