The Democrats are still playing old-school politics and it cost them the election. The Republicans have apparently given over to the oligarchs. A party that actually represents the working class could break the stranglehold that the two-party system has on us.
I think the more valuable things would be to do something like Grover Norquist and create a firm pledge that requires candidates to propose and or vote for ranked choice voting nationwide, Automatic voter registration, election holiday, capped private donations, removing corporate donations and loopholes, and maybe term limits.
Start with these pledges at the local and state levels and make it crystal clear that we will primary the shit out of anyone who won’t sign or flips on their pledge.
So many of the issues with the current parties start because our elections are not fair or representative. If we fixed that it would push out the people only interested in power but not directly threaten either party or cause a spoiler effect.
