A few Modest Proposals:

US Senate stays at two Senators per state. Votes in the US Senate are weighted by state population. Call it the "US Senate Weighted Vote - USSWV." John Barrasso and Cynthia Lummis each get one USSWV, as they're from Wyoming. Bernie Sanders gets 1.1 USSWV. Dianne Feinstein and Alex Padilla get 66.1 USSWV each. There are (about) 1093 USSWV; laws pass with a majority of USSWV.

Let politicians draw any odd shape they want for electoral districts, as long as they have uniform populations. If the GOP or Democratic candidate wins with more than 2/3 of the votes cast, they are disqualified and the candidate with the second-highest vote total is elected.

Juries are more or less randomly selected from qualified citizens to determine the outcome of some of the weighiest issues placed before the commonwealth. Let's pick legislators the same way.

Spouses are barred from running for offices previously held by the other spouse.
