@skematica Eh…I'm currently a registered Green, but I'm not a fan of Jill Stein.
Anyway, in our current setup, third parties never have much of a chance. I may be registered Green, but in the current environment--particularly if the election goes badly--I think the left is better off coalescing behind the Democratic banner to fight the right wing, rather than dividing. We can have the usual left-wing circular firing squad later. You just have to look at the GOP to see where ideological purity tests lead. They should serve as a cautionary tale.
