Have you actually tried to do this?
Personally, I’ve tried to reform the democratic party from the inside for the last 20 years, and I’ve given up, I think it’s a foolheardy endeavor.
Corporate interests are thoroughly entrenched in the party at every level. The democratic party has set up so many structural hurdles that make it nearly impossible for a progressive challenger to have a shot.
Take a small example: when I was volunteering for two different local progressive challengers, they both had extreme difficulty doing basic campaign things like printing flyers, road signs, pamphlets etc. Why? Because the Democratic Party has a explicit policy of blacklisting any vendor who aids a progressive challenger. No print shop would print our flyers.
There are so many structural hurdles like this set up by the Democratic Party, I would encourage you to volunteer and find out how bad it is for yourself.
It kinda seems like immigrants and anti-war protesters made it to the top of the list this time.
