I don’t see how you expect to get democrats to support voting reform when it goes against their interests and you support them whether they do it or not. That’s the fundamental problem with what you’re saying, you recognize that the current system is dysfunctional, but you’re expecting that system to function well enough to enact the changes necessary to make it functional.

You’re saying you want the people in charge to give up the systems they depend on to maintain their own power, to act in a way that very directly goes against their own interests, and I don’t see what your plan is exactly to force them to do that, beyond asking nicely while giving them full unconditional support.
