1) This would be a terrible move, and I would love to see CONSERVatives adopt CONSERVation as won of their principles. Protecting the environment should never, ever have been adopted as a strictly "liberal" position.
2) The GOP has historically pretty much done what business wanted it to do, so long as it didn't directly conflict with its moralist base, LOL. Its environmental policy has not exactly followed a principled pattern.
3) Every five years, the threshold for when Republicans were "sane" gets bumped up five more years into the future, LOL. In 80 years, Democrats will be talking about how Reagan was a liberal for his time because the Democratic Party of his day had two Senators from Alabama or some bullshlt like that, and they'll say Reagan would be a Democrat today. You can make your case about the current GOP - an institution that I have as much issue with as most any Republican - without feeling the need to praise Republicans from history that still represented the basic conservative principles that you would take huge issue with.
Listen, I am a conservative: a conservative liberal, of course, but no damn Commie for sure. You do not have to keep loyalty to the party that has left you: there is no place for a conservative in the GNP.
