If the dog won't herd the sheep any more, they will shoot the dog. The Republican Party is that sheep dog.
There are two ways it survives. Either we stop trying to take the party back and make it serve the people, in which case they stop gutting it in an attempt to 'remove the cancer' that is us (that's how they look at us), or we take the party back and maintain it ourselves.
Rather than let us have the G.O.P. they will destroy it. Make no mistake. If you think they're sentimental about it, you don't know these sociopaths very well.
It isn't fallin apart (insider Oklahoman joke there), it's undergoing surgery. It's being cut up. If it winds up no bigger than the LIbertarian Party, well, then they might consider it harmless enough to let us have control of it.
