Why did Nebraska decide to have a unicameral government instead of a bicameral government?

U.S senator George William Norris is considered the
founder of the Nebraska Unicameral legislature.  He and other advocates of the
unicameral system believed that it allowed for simpler and more efficient bill to law
process, without having each body to pass a given bill separately. That the unicameral
system would cost less, and put more scrutiny on the one body and made the legislators
more accountable. Unicameral advocates also believed a one body system would make
lobbyist less powerful because the process would be more public. In addition, the
elimination of the conference-committee, which Norris and others believed was the most
secretive and easily corrupted aspect of a bicameral legislature. Because these factors
Nebraska voters eliminated their bicameral system in favor of a unicameral one in
1937.
