Since I live in a solid blue state, I'll be voting Green.

I can't in good conscience vote for a candidate who sponsored a coup in Honduras, takes money from the brutally repressive Saudi government, and represents the financial interests that are selling America down the river. And I believe Trump would, at best, be a figurehead who would (if the deal offered Kasich holds) let Pence be de facto President. That presents its own problems given his fiercely Religious Right/anti-labor/pro-TPP record in Indiana, but I'm in some ways even more worried about Trump trying to exert himself. Considering he seems to have no idea what even he'd do.

For the record, I do think the Green Party can become a thing if they shed their "hippie" baggage which puts off most people, it makes them seem like the "kumbaya party" with a single-issue focus on environmentalism. Them becoming relevant probably would mean being absorbed into a broader Progressive Party, uniting with left-wing factions of the Democrats who have much more mainstream appeal in a de facto restoration of the New Deal coalition. If the age-based demographic decline in the Republican Party continues to hold, and the Democratic establishment continues Hillary Clinton's policy of trying to reel in moderate Republicans, the next partisan realignment could be along those lines though. Between "establishment Democrats" and "progressives."
