Yes, they do. Eisenhower, Nixon, and both Bushes were RINOs. Reagan was the exception.
I've been writing on the topic of this article for ten years, actually developing explanations for the mechanics of how liberty works versus why government control fails. It really isn't hard to explain to people why a bureaucrat listing an endangered species has a motive to KEEP it endangered. It isn't hard to show that paying somebody to grow more is cheaper and quicker. It isn't hard to show how expensive is a massive bureaucracy of cops, prison guards, psychologists, interpreters, clerks, lawyers, and judges just to maintain a criminal justice system that thrives on the children of immoral parents and educators. If all we do is shout "Liberty, God, Morality..." we have not informed the voter as to how we intend to see to it that many of society's ills are cured. Instead, the MSM will fill in those memes with their usual "solutions." We must have those instructive libertarian sound-bites on the tip of our tongues for the little media time we get.
That IS the problem of MAKING conservatives out of voters, people who will reliably go to the polls to save themselves from what at first seem like easy coercive "solutions": "just pass a law that makes them do it..." To me, it is absolutely shocking the degree to which the political glitterati have ignored this fundamental necessity. I have offered candidates my assistance for nearly a decade to deaf ears. They all want to run away from doing the homework it takes to be facile in each of the issues. It is a steady, tedious, and detailed process of learning examples and refining the language of delivery, but that homework MUST be done.
Conservatives cannot win by catering to voters; we win by teaching voters to be conservatives. Reagan did that, that's why he won.
