Should state legislatures be unicameral?

Honestly the only check and balance that is absolutely necessary is an independent judicial system. After that, history has shown that they produce gridlock and kludges.

All legislatures should be unicameral, and also if PR is not a possibility than multi-member districts should be abolished too. In NJ everyone has 3 state legislators (1 Senator and 2 Assemblymen) which is not only unnecessary but confusing.

PR is valuable, but I personally think that if citizens had only one woman or man who represents them in the state capitol that they would have a more direct channel into state politics, while also giving state legislators the higher profile that they really deserve.

Like Nebraska?

We know the senate exists to give smaller states a bigger voice, but why do states need a senate?
Only one is needed.

To give a bigger voice to less populated regions in a state. Let the States decide whether their legislatures are unicameral or not.

Why should less populated regions have a bigger voice?  Are people there more important than other people?

Exactly--upper houses existed typically to give an outsized vote those in rural areas compared to urban areas. Like many aspects of 1780s republicanism, this sort of structure is totally useless for modern politics. Bicameralism does nothing for the legislature but make it more difficult to pass laws.

This is also why I would replace Congress with a unicameral, parliamentary MMP House of Representatives if i could, though I doubt even a constitutional convention is feasible politically, much less that sort of reform.
