Robert Campbell's post raises all kinds of good questions for discussion. Being somewhat sympathetic to the argument Gus DiZerega made in the comments, I'd like to add a thought or two.
My sympathy for Gus's argument is really about how I see myself: I've always thought of myself as "on the left" but believing that economic freedom was a better means to many of the left's ends than was interventionism or socialism. Perhaps this is the result of being in academia and finding that I'd largely rather hang out with my leftist colleagues than free-market conservatives of the policy world sort. I find too many conservatives less tolerant of difference than I might like them to be; too quick to demonize the left in the very same ways they object to being demonized by the left; and generally too dismissive of the world of academia, both as it is currently structured and inhabited, and as a vocation/avocation. Hayek's classic essay "Why I'm Not a Conservative" captures a few more of my complaints.
In the way that leftists describe libertarians as "conservatives without the sex and drugs hangups," I'd prefer to describe myself as a "leftist without the capitalism hang ups."
Of course none of this, I think, changes the substance of my libertarianism. Robert is quite right in describing the substantive issues, and I do agree that there are things equal to or greater than defeating George W. Bush on the libertarian priority list. (Although I will note that if I was coerced to vote and had to vote for one of the two major parties, as of right now I'd vote for Kerry. Bush is the worst of both worlds - fiscal profligacy and bad on civil liberties/rights, not to mention that whole war thing.) Still, I bristle every time someone calls me a "right-winger" or says that libertarianism is "on the right." Yes, it tries to explode the simple binary opposition of left-right (one of the few binary oppositions that sophisticated French-influenced leftist cultural theorists are not passionate about deconstructing), but if I have to choose, I'm on the left.
