It would be more effective to focus on supporting a progressive candidate for the DNC chair. The prospect of establishing a viable third party is extremely challenging, given the existence of nearly 20 “progressive” third parties that have struggled to gain traction. As someone who served as the chair for the Ohio Green Party, and was a platform builder for an already defunct progressive party, I have firsthand experience with the obstacles such efforts face. I’ve learned from my mistakes. The Progressive Caucus, Justice Democrats, Working Families Party, and more are great organizations to organize with. AIPAC out-funded progressives, but now people know that AIPAC is the reason the Democratic Party is terrible, and now volunteer and donation signups for progressive orgs have raised.
