> Citizens United

I agree.

Include ranked choice or quadratic voting + repeal CU and a lot of things could improve quickly.

Terms limited to 25 years and age 65 at time of election.

I agree and support term limits, but also not certain it can fix anything.

Legislators are (with rare few exceptions) not independent from the power of their party (meaning, they either align with party line or don't stand a chance of being elected). And each party has a nearly endless supply of new corrupt people to substitute in. Even if we had single term term-limits for every role, each party will keep cycling in new corrupt party-aligned people into those roles.

What we really need is a system where legislator are in a position that it is not feasible to corrupt them. It's fun to think of ways of designing such a government, but of course it will never be allowed by the powers that be.
