No flaming, but your 'reasoning' is why I cannot vote Libertarian. While the Libertarian party does stand for fiscal and 'social' conservativism, it also stands for moral liberalism. At this point in our history, I think taking stands on moral issues is a more important thing for me to do.
I hesitate to call myself a moral liberal -- I favor permitting a lot more than I indulge in or even want to indulge in -- but moral issues are the one major area, where I break from the GOP. However, I think the Democrats are just as bad, if not worse, in issues of personal conscience.
However, at this point of history, I believe national security is the most important issue -- without it questions of morals all become rather moot in the face of day-to-day survival -- which is why Bush is guaranteed my vote in November.
