text: Most counties do not have home rule.Any policy changes proposed in different areas of the state must be approved by the entire Alabama legislature and, frequently, by state referendum.One criticism of the current constitution claims that its complexity and length intentionally codify segregation and racism.Alabama's government is divided into three coequal branches.The legislative branch is the Alabama Legislature, a bicameral assembly composed of the Alabama House of Representatives, with 105 members, and the Alabama Senate, with 35 members.The Legislature is responsible for writing, debating, passing, or defeating state legislation.The Republican Party currently holds a majority in both houses of the Legislature.The Legislature has the power to override a gubernatorial veto by a simple majority (most state Legislatures require a two-thirds majority to override a veto).Until 1964, the state elected state senators on a geographic basis by county, with one per county.It had not redistricted congressional districts since passage of its constitution in 1901; as a result, urbanized areas were grossly underrepresented.It had not changed legislative districts to reflect the decennial censuses, either.In Reynolds v.Sims (1964), the U.S.Supreme Court implemented the principle of "one man, one vote", ruling that congressional districts had to be reapportioned based on censuses (as the state already included in its constitution but had not implemented.) Further, the court ruled that both houses of bicameral state legislatures had to be apportioned by population, as there was no constitutional basis for states to have geographically based systems.At that time, Alabama and many other states had to change their legislative districting, as many across the country had systems that underrepresented urban areas and districts.This had caused decades of underinvestment in such areas.
