Because I live in a county and state where being a Libertarian would shut me out of any ability to influence the primary elections that actually matter.
An alternative title for this post, considered but rejected, was Why I Should Be A Libertarian. I spent most of the day yesterday in a hospital room watching endless CNN coverage, all delivered in baited breath, of an incident in which a 400 lb. alcoholic didn't have a stroke. My first thought on the matter was, "That's sad." My second thought was, "Why do I care about this?" My third thought was, "Why do they care about this?" I didn't learn until this morning that a horse had accomplished a feat greater than anything the 400 lb. alcoholic will ever perform, news that I actually do care about.
It was as though someone who had actually achieved something in this life had died.
5/25/2008 Update: I now rather regret writing this, as I had no idea at the time that Kennedy suffers a problem much more serious than a stroke, and I particularly regret that a swarm of Instapundit readers are coming to our blog from an Iowahawk trackback through this post, which is utterly meaningless and was written in a bad frame of mind after spending a considerable time at a hospital.
Anyway, welcome Instapundit Iowahawk trackback readers! If you're interested in reading further here, I'd suggest clicking the link to Ken's posts at the upper right, as he's really our most talented and funniest blogger. I'm just a sub on Ken's team.
Damn a lot of people read Instapundit!
