A more viable attempt at secession might look like: perhaps a new Hawaiian independence party forms with massive (>80%) and sustained (>20 years) on-the-ground support, with all federal representatives coming from this party. Eventually this party might convince the federal and enough state governments to support a constitutional amendment recognizing a specific independence referendum. That's very theoretical but I hope illustrates what actual secession might look like.
Also consider that before the U.S. civil war the southern states voted against Lincoln, the northern candidate, in fact he was not even on the ballot in many of them. If the enslaved people in those states had been able to vote things would have gone differently. So we have a unique and terrible history of states seceding based on a minority's wishes.
