I’m like you here, I truly believe the Murdochs of the world–and most definitely the Kochs–want a Walker or a Kasich far over and above any desire to see a Carson in there – and not because he’s black, but because they see Carson as a very feathery lightweight in the brains department and is a total unknown with how far they can puppet him like they know they can a Walker and (to a somewhat lesser degree) Kasich. They don’t want a Bush because of the toxicity involved.
If making hordes of money and not really caring to try to dictate any policy were their game, I don’t see why they all wouldn’t be behind a Democrat like Hillary … just look at how well their bank accounts have done under Bill Clinton and Barack Obama. However, they’re not just greedy, they want to control our very lives as well (so they can manipulate what we are able to do and make us miserable).
