Unicameralism
From Ballotpedia
Unicameralism is the practice of having only one legislative or parliamentary chamber.
Within the individual United States, bicameralism was usually modeled upon that of the United States Federal Government, with the upper house, in analogy to the states, consisting of State Senators who represented geographic areas independent of their population, typically counties.
In 1964, a U.S. Supreme Court decision in Reynolds v. Sims voided this arrangement as applied to states. In response to this most states replaced the fixed geographic boundaries with more flexible State Senatorial Districts, which are re-drawn after every decennial census. In such cases the term of office for the upper house will usually be longer and the number of seats lower than for the lower house. Like the districts of the lower house they are now subject to the process of gerrymandering, with boundaries manipulated to favor incumbents of both parties (as in California), or to favor the majority party (as in Maryland and Texas).
Nebraska is currently the only state with a unicameral legislature. Nebraska's state legislature is also unique in the sense that it is the only state legislature that is entirely nonpartisan.
Michigan unicameral petition drive
An unsuccessful effort to collect petition signatures was launched in January 2006 by Unicameral Michigan, a ballot question committee registered with the State of Michigan, to provide for an amendment to the state's constitution to change from a bicameral to a unicameral legislature. It failed to qualify for the November 2006 ballot.
