Part Two:
Your concern about Congress picking the president is a paper tiger.  The electoral college delegates are thought to be "pleged", but in reality, if the feces hit the proverbial oscillating device, they would conspire amongst themselves and avoid the House.  There are a very few state laws here and there which provide for some penalty if they don't vote as pledged, but they have never been enforced, likely wouldn't be enforced, and if by some strange situation they were, they electors would likely be pardoned or get a slap on the wrist.  Many electors thought history have not voted as pledged and not a single one has had any legal problems.

On the state level, Hawai`i could use a Green party because the corporations and rich folks are already setting the agenda, having a major impact on the budget and who can afford to run for office.  As far as the presidential race goes, if Hillary *needs* Hawai`i to win, she has way bigger problems than the Greens.
