So it turns out that Sarah Palin was not a member of the Alaskan Independence Party as I previously thought (having heard initial reports and being otherwise engaged since). I do not find it terribly relevant if her husband was, as he is not actually running for office.
My thanks to ebartley for the link. This is, of course, why discussion in good faith is so useful.
I'll confess I'm relieved, as I don't see how you could nominate for the VP spot someone who supported Alaska succeeding from the Union. Not that I am thus persuaded to vote for Palin McCAin, mind. I have more than enough policy reasons why I favor Obama. But I prefer to know the actual state of affairs -- if for no other reason than to not regard my opposite numbers as utter lunatics.
