Hawaii is weird. I don't think we'll ever know how it votes "by default."
You ever realize how it loves incumbents too? They voted for Johnson in a landslide even bigger than his national landslide which I know it's always been blue, but still! Nixon won it the second time, Ford always won it which is impressive for Republicans, they voted for Carter as and incumbent and was almost on center for Reagan, and Bush only lost 54-46 there in 2004. As for Bush in 1992 and Clinton in 1996 I believe both of them did better the second time there too.
