Okay, yes, I see what you mean and can agree. Still I believe that this can only bring about meaningful change if it's part of an activist push for election reform.

The local level is important and easier to manage, because the power brokers, the keys to power are not that much more powerful than you are. But at a certain point the keys to power become way too influential. To reach the top in any party, you have to play by the parties rules and neither one will let you lessen their individual members influence. You would need wide ranging political agreement and cooperation (and good luck with that) or you have to change the game by redistributing power away from big players and back to the people. And that can imho. not be achieved in a highly partisan two-party system.

Or, maybe it can be, but the odds are incredibly stacked against you.
