If you want to vote third party but don’t like the greens, the party for socialism and liberation is running de la Cruz on a platform of Palestinian statehood!
The two state solution has been the platform of most of the world for decades, I think Democratic president Bill Clinton most recently undertook a major effort to make it happen, but the two parties of course couldn’t agree and started fighting instead.
PSL and Greens, due to their unpopularity and belief in ideology over consensus, will never actually be in a position to broker internationally impactful diplomatic efforts.
