I think our government would be more effective, more representative, and we would all be better off if:
All judges and justices, including the US Supreme Court, were appointed by independent commissions. Nonpartisan commissions, or if they can’t be nonpartisan, fairly weighted based on party affiliation.
All voting districts were also set by independent commissions. Nonpartisan commissions, or if they can’t be nonpartisan, fairly weighted based on party affiliation.
Corporations were determined to not be people and only people could make political contributions. Set a maximum contribution per person, and that includes the candidate. One person, one vote, no million-dollar contributions, no political PACs. No dark money. If that can’t provide enough money for each candidate to present their qualifications, then provide a base level of federal or state campaign funding for qualified candidates.
Maybe we can’t reach the ideal of one person one vote, assuming that is still an ideal, but these approaches might get us closer to it. And none of this would be that hard to do, if there was a will to do it.
