I'm with you on that!

An additional fun (?) fact is that Nebraska has only senators, not state representatives, due to having a unicameral legislature unlike all the other states and the federal government. The members of Nebraska's single-house legislature are customarily called "senators," and they're also officially non-partisan, though in the modern era this is just a fig leaf and their partisan political affiliations are clear.
