When Jessie Ventura was Governor of Minnesota and before he became a semi loony conspiracy theorist he argued that the bicameral legislature allowed both houses to pass the blame to each other.
There is actually a news story on this available on the internet (and it goes back to 1999.)
https://www.nytimes.com/1999/08/22/us/political-briefing-ventura-s-mission-turning-two-into-one.htmlAs Mr. Ventura sees things, the bicameral, or two-house, system of legislating is gummed up with partisan bickering and, worst of all, allows legislators to duck accountability by saying that shortcomings were caused by members of the other house. He wants the current two-house Legislature in Minnesota to authorize a statewide vote next year on whether to rewrite the state's Constitution and shift to a unicameral system.
