Yeah, it seems very unfair. If Party A has 60% of the seats in the state legislature, and Party B has 40%, then intuitively it feels like Party A should get 60% of what it wants. But as you said, Party A actually gets more like 100% of what it wants.

This is a thing where having more parties would really help. If there were (say) 4 parties, each with ~25% of the seats, then they would have to bargain with each other and form coalitions, which I think would be a really healthy process for democracy.

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.
