The Alaska Independence Party got more than its typical share of press after the discovery of the Palins' connections thereto. So we may collectively know a little more about its substantive views than we did previously; nonetheless, for insight into the manner in which the AIP nominates its candidates during the primaries, and for insight into how it wishes it could nominate its candidates, check out this opinion.
I think that Judge Fisher's opinion is exceptionally good. I didn't have a strong preexisting feeling on the merits of the dispute, but in the end, I was entirely persuaded that Judge Fisher was right. Political parties have associational rights. But those rights don't extend to only allowing "approved" party members to be the party nominee. At least in contexts similar to those that exist here.
I'm on board for this one.
