What?  Talk about revisionist history. "Dole brought Democracy to Hawaii..."
No he didn't, he establish an oligarchy of wealth business men and landowners both in the bayonet constitution and the "republic" of Hawai'i. There were land and wealth minimums that needed to be met to be awarded the right to vote.  In the elections that brought about the Lunalilo and Kalakaua administrations ALL subjects had the right to vote. 
"The real effect of the change...was empowerment of the Polynesian citizens in Hawaii."  NO it completely disempowered them!  You don't have to go far for evidence just look at the cabinets installed in these governments, you're not gonna find Hawaiians or others.  How about you take a peak at the 20,000+ names on that petition to the US gov't.  Then take a look at reaction to the Wilcox led effort to retake Hawai'i, many Hawaiian leaders and intellectuals that had little to no involvement were jailed and executed by the traitorous groups of rich white americans
