1. I do think it is important to stagger the Senate elections in order to avoid massive turnover in the legislature all at once, which could effectively bring Congress to a halt, hurting the stability of our government.
4. While there are certainly challenges representing a large base of constituents I think it makes sense to cap the number of representatives because they need to be able to work together to get things done. We see how hard it is for them to work together now with 435, and increasing that number would likely make it even more difficult. In general, I think the structure of Congress makes sense.
