Horseshit! Reagan was a conservative, not a libertarian. He gave one interview in his entire political career about Libertarianism. That was to the Libertarian Party rag, Reason magazine. That interview came the year before he ran for potus against Pres Ford. Reagan was politicking, mining for possible votes. Reagan was the master rhetorician and used similar language when it came to the Republican Party and conservative principles.
Here's what Reagan said. You can claim he was not being honest and was just fishing for votes if you want, I think much more of the man.
If you analyze it I believe the very heart and soul of conservatism is libertarianism. I think conservatism is really a misnomer just as liberalism is a misnomer for the liberals–if we were back in the days of the Revolution, so-called conservatives today would be the Liberals and the liberals would be the Tories. The basis of conservatism is a desire for less government interference or less centralized authority or more individual freedom and this is a pretty general description also of what libertarianism is.
Now, I can’t say that I will agree with all the things that the present group who call themselves Libertarians in the sense of a party say, because I think that like in any political movement there are shades, and there are libertarians who are almost over at the point of wanting no government at all or anarchy. I believe there are legitimate government functions. There is a legitimate need in an orderly society for some government to maintain freedom or we will have tyranny by individuals. The strongest man on the block will run the neighborhood. We have government to insure that we don’t each one of us have to carry a club to defend ourselves. But again, I stand on my statement that I think that libertarianism and conservatism are travelling the same path.
