> This is a thing where having more parties would really help.

Using a "first past the post" voting system structurally results in a two party system, because if there are more than two viable parties then the two parties most similar to each other split the vote and both lose to the third, which gives the first two an overwhelming incentive to merge with each other.

Score voting or STAR voting fixes this and allows you to have multiple parties. (Avoid IRV or similar systems, nearly anything is better than FPTP but if you're going to do it at all then do it properly.) Any states that could enact this via referendum are encouraged to do so.
