Are there any (relatively unbiased) statistics on who on the islands support this and the percentage of "Native Hawaiians" there are? I ask because their message seems nice enough, but this really seems like a nutjob movement when I think about the likelihood of self reliance and fair treatment to "non-natives" in the state.

good question! would like to know the answer myself. I know there are similar movements in Texas and Alaska. Here's the wiki on the Hawaiian sovereignty movement: http://en.wikipedia.org/wiki/Hawaiian_sovereignty

I did find census information that could help clear this up a little bit.

The 2008 estimate for people living in Hawaii is 1.28M people. With that same estimate, those 9.1% of those are of Native Hawaiian descent. A large percentage, 18.3%, are of two races. Those are probably of Hawaiian and other racial background. So, for a Native Hawaiian movement, there are a possible 350 thousand out of 1.2 million people in this government. That's not a number of supporters which could be more or less than that number (but I'm hedging my bets on less).

After typing that much information about the heritage of people I don't know, the whole movement sounds the least bit racist towards a minority population. It seems to me that Hawaii isn't the island nation that it once was.

There is a similar movement in Alaska too.

Someone I know thinks Texas might become a self-sufficent nation. Soon we will be back to thirteen colonies.
