Arguments for and against bicameral state legislatures?

[Xeuma]

All states except for Nebraska have two chambers in their legislatures, the upper house being smaller than the lower house. In light of Reynolds v. Sims (requiring state senate districts to be apportioned to have roughly equal populations), what is the purpose of a state senate? In my personal view, state senates are an outdated body that no longer serve a purpose.

What are your views on state senates? Do they serve a meaningful purpose? Should / will the states abolish them?

I agree, but I think approval voting is superior to instant-runoff voting, just as a function of Bayesian regrets. The range voting website has a graphic demonstrating this, I can't link it though until I have 20 posts.

What was the reasoning behind  Reynolds v. Sims, anyways? If it's democratic enough for the federal government, it seems weird that it would be unconstitutional for the state governments. I wonder if it will get overturned.

The problem is that the federal government is extremely undemocratic.
