Interesting, I wonder how many invisible third parties exist at the state or regional level that would be represented in a better system.
That being said, this state government seems rather large for Minnesota, a state with a population of six million people. 67 senators and 134 representatives, and that's within the clunky three-branch system of government copied from the US Federal Government. Those numbers are bigger than California's which has a population that is five times larger.
We're at about one legislature for every 30k people. It was one per 20k in 1973, one per 12k in 1919, one per 6k in 1889, and less than one in 2k when Minnesota was a territory in 1858.
I'm not sure what the right ratio is, but the level of disenfranchisement is palpable.
