@engineer,
I would say it is a mystery, but it really isn't. I am not good at putting words together in a concise and intelligent way, so I'll just say it is a concerted effort on the part of the big wigs on the conservative side, they seem to have a good enough message to win local votes. We will see if it works this time nationally in 2016. Democrats (or all others) are not half as good at selling their message, unfortunately. What I have taken away from the midterms is that we should start focusing on the basics again, as in "it's the economy, stupid."
