Comparison of U.S. state governments
In the United States, the government of each of the 50 states is structured in accordance with its individual constitution. In turn, each state constitution must be grounded in republican principles. Article IV, Section 4, Clause 1 of the United States Constitution tasks the federal government with assuring that each state's government is so organized.
All state governments are modeled after the federal government and consist of three branches (although the three-branch structure is not Constitutionally required): executive, legislative, and judicial. All state governments are also organized as presidential systems where the governor is both head of government and head of state (even though this too is not required). The government of each of the five permanently inhabited U.S. territories is modeled and organized in a like fashion.
Each state is itself a sovereign entity, and as such, reserves the right to organize in any way (within the above stated parameter) deemed appropriate by its people. As a result, while the governments of the various states share many similar features, they often vary greatly with regard to form and substance. No two state governments are identical. The following tables compare and contrast some of the features of U.S. state governments.
With the exception of Nebraska, all American state legislatures are bicameral, meaning there is one legislative body separated into two units. Nebraska eliminated its lower house with a referendum during the 1936 elections. Also, some systems, such as New York's, have two legislative bodies while never technically referring to them in the state constitution as a single body. These dual systems are generally considered bicameral.
While only 13 states have a filibuster, there are often restrictions on the majority a state needs to raise taxes.
|Alabama||The Alabama State Senate allows a filibuster, and has a general three-fifths requirement to enact cloture. A simple majority of 18 is acceptable when dealing with the budget and redistricting.|
|Arkansas||Arkansas, along with Rhode Island, is one of the only states that requires a supermajority to pass a budget. A three-fourths majority is required for appropriations, except for education, highways, and paying down the state debt, which require a simple majority.|
|California||From 1933-2011 there was a two-thirds requirement for general fund appropriations for purposes other than public schools (Const., Art. IV, Sec. 12). Because the Legislature typically passes one main budget bill, the requirement effectively applied to the whole budget bill. There has been a two-thirds requirement for tax increases since Proposition 13 in 1978. In 2010, voters approved Proposition 25, eliminating the 2/3 requirement for the budget, but keeping it for tax increases.|
The Governor is the chief executive official in each state.
