I think some state legislatures actually predated to federal one. I know some states had constitutions before the US did, but I don't know if they included the legislature structure.
Why only one house or three? What exactly would that fix? Sure you eliminate most deadlock, but how does that representation? Also, is deadlock really a bad thing in all scenarios?
