Not being a conservative myself, I don't have a dog in this hunt, exactly. But remind me again, who was the conservative who had a decent shot at the Republican nomination in 2000? John McCain?
And if the Republicans had nominated a true-blue conservative, rather than a "compassionate conservative," in 2000 would he have won?
As a libertarian myself, I'd love to see the nation run under small-government principles (which is part of what people are talking about here), but I also recognize that there's no very substantial base of electoral support for that. (And the Libertarian Party hasn't done anything to improve things; quite the contrary, it's probably a net negative.)
You want a True Conservative in the White House? Persuade a majority of Americans that true conservatism is what they want. If you want to start on that, you might take a look at PorkBusters Hall of Shame Grand Prize Winner Ted Stevens (R-AK) and ask if he's the best face for the Republican Party. Because right now, he is the face of the Republican Party.
