But we still need a DNC and state parties if only to facilitate primaries, that’s a very important function. a month ago when we got a DNC chair who will let a fair primary happen… Now is the time to rally around the new Dem party, not make a new one

Totally agree here with emphasis on the new part. Surge the turnout in the primaries. Without ballot access in every state it’s just not realistic to expect a 3rd party can rise up and replace the Democratic party in 2026 or 2028. Except in states with direct ballot initiatives to switch to ranked choice voting, but even that is only a solution for at best the election after getting that voted into existence.
