Sure, there are some things the parties disagree on. That's what they use to sow division and keep the system in place. But I listed four things that both parties engage in. These are just some examples of norms that are terrible for our democracy but that will not go away so long as we have this current voting system.
You asked for a plan, here it is: vote blue when you have to but the work does not stop at voting. Get in contact with grassroots organizations and make an actual difference. Or we can just tell people to vote blue every four years and wonder why Americans don't feel represented in government.
You're really good at sticking to your point and ignoring all else. I've reiterated twice now but you're clearly going to keep ignoring. (While also being sanctimonious.) I've already said we have to vote blue, what more do you want? Just to argue?
