Why is Hawaii so Democratic? Why did West Virginia flip?

[Nyvin]

In the case of West Virginia, it used to be an extremely unionized state with a large uneducated population,  both things benefited the Democrats tremendously.

Nowadays it's the education population that benefits the Democrats, and the unions are mostly all gone.    That and perhaps a smaller issue is the state being against climate change, and the Democrats adopting that into their framework.
