According to ABCNews, Sarah Palin was a member of the Alaska Independence Party during the 1990's, and even attended an event they sponsored in 1994.
The Alaska Independence Party is a group who wants Alaska to secede from the United States and form its own independent country.
I'm not sure the extent to which Palin was involved with this organization, but it appears that she was a member, and did attend events. This has been confirmed by ABCNews through the chairman of the AIP, Lynette Clark.

McCain's choice for VP is becoming more and more difficult to believe. Was this woman vetted at all?
I wonder how Republicans would react if Obama's running mate was shown to have been a member of a group advocating secession from the United States?
