That is why state government elections are so important right now.

• States all need a representative voting system implemented. Ranked Choice, STAR, it doesn't matter, just get something that's not a single ballot practice.
• Each state also needs it's electoral college distributed to top candidates proportionally, by either direct vote count or by counties won. This at least somewhat neutralizes the effects of gerrymandering.

Better systems can come later, this should be a top priority for going forward. As it stands the American public doesn't stand a chance at being represented and that needs to change first before other fixes can actually come about.
