None. I stopped self-identifying as a Democrat about 4 months ago. First time in my life I haven't been affiliated. And the idea I'd ever even remotely consider voting for a Republican or Libertarian is repulsive to me.
Thus, leftists like myself are homeless. The Green Party was corrupted by that self-serving hack Jill Stein. There's a movement to branch out into the People's Party of America from the Green party because it was so badly ruined by her over the last 8 years and too much of the corporate taint that stenches up the duopoly.
But really, there's no true option if we want any political influence whatsoever than to make waves within the Democratic party. It's what Bernie did and why his repudiation from within the establishment was do crushing to so many of us. Thus, folks like myself, with the views I have, will be doing my damage from the inside. Trying to slowly but surely go full insurgent on the Democratic party by electing progressives and leftists around the country, one by one.
Thankfully where I live, I have a real progressive to get out and support that is a Democrat, Julie Oliver, for Congress in TX-25. I'm nonplussed about Senate and the President races but will likely vote for the Dems in those races if it appears close enough (within 7% or so). Otherwise I'll go Green or write-in where I can.
Long winded answer but it's necessary to fully underscore my position.
