    Trifecta history

    A state government trifecta is a term that describes single party government, when one political party holds the governor's office and has majorities in both chambers of the legislature in a state government. Between 1992 and 2023, Iowa was under the following types of trifecta control:

    • Democratic trifecta: 2007-2010
    • Republican trifecta: 1997-1998, 2017-2023
    • Divided government: 1992-1996, 1999-2006, 2011-2016

    Vacancies

    See also: How vacancies are filled in state legislatures

    If there is a vacancy in the Iowa General Assembly, the vacant seat must be filled by a special election. The governor of Iowa is required within five days of a vacancy in the General Assembly to call for a special election. If the vacancy happens in session or within 45 days of the session convening, the governor must call for an election as soon as possible with at least an 18-day notice. All other special elections require a 40-day notice as long the election does not happen on the same day as a school election within the district.[13]

    Redistricting

    See also: Redistricting in Iowa

    The Legislative Services Agency prepares redistricting plans for approval by the Iowa State Legislature. According to All About Redistricting, the Legislative Services Agency (LSA) consists of "civil servants committed to nonpartisanship and otherwise charged with tasks like legal and fiscal analysis of state legislation and state government oversight." The LSA is assisted by a commission, which consists of the following members:[14]

    1. one member selected by the majority leader of the Iowa State Senate
    2. one member selected by the majority leader of the Iowa House of Representatives
    3. one member selected by the minority leader of the Iowa State Senate
    4. one member selected by the minority leader of the Iowa House of Representatives
    5. one member selected by the first four members

    The members of this commission cannot "hold partisan public office or an office in a political party, and none may be a relative or employee of a federal or state legislator (or the legislature as a whole)."[14]

    Working with this commission, the LSA drafts congressional and state legislative district lines. The maps are presented as a single bill to the state legislature, which may approve or reject the bill without altering it (the legislature can provide feedback). If the legislature rejects the plan, the LSA must draft a second proposal. If the legislature rejects the second proposal, the LSA must draft a third, and final, set of maps. If the legislature rejects this plan, it may then approve its own maps. Since the implementation of this process in 1980, the state legislature has never chosen not to approve an LSA proposal. Redistricting plans are also subject to gubernatorial veto. In addition, the legislature may repeal or revise the maps at any time, though it has never done so.[14]

    State law establishes the following criteria for both congressional and state legislative districts:[14]

    1. Districts must be "convenient and contiguous."
    2. Districts must "preserve the integrity of political subdivisions like counties and cities."
    3. Districts must "to the extent consistent with other requirements, [be] reasonably compact–defined in terms of regular polygons, comparisons of length and width, and overall boundary perimeter."

    In addition, state House districts are required to be contained within state Senate districts "where possible, and where not in conflict with the criteria above." It is explicit in state law that district lines cannot be drawn "to favor a political party, incumbent, or other person or group."[14]

    2020

    On November 4, 2021, Iowa Gov. Kim Reynolds (R) signed new congressional and state legislative maps into law after the state's Legislative Services Agency had proposed them on October 21, 2021. The Iowa legislature approved the maps on October 28, 2021, by a vote of 48-1 in the state Senate and 93-2 in the state House.[15] The legislature could only vote to approve or reject the maps and could not make any amendments. These maps took effect for Iowa's 2022 congressional and legislative elections.

    2010

    See also: Redistricting in Iowa after the 2010 census

    According to the U.S. Census Bureau, Iowa's population increased 4.1 percent between 2000 and 2010, growing to 3.05 million. This rate was less than half of the national growth rate of roughly 10 percent between 2000 and 2010.[16] Due to this slow growth, the U.S. Census Bureau determined that Iowa would be represented by four members of the U.S. House of Representatives, rather than the five seats Iowa had during the 2000-2010 decade.[17] Most of Iowa's growth occurred in the urban and suburban areas of the state, while most of the rural counties grew slowly or lost population.[18]

    On March 31, 2011, the Iowa Legislative Service Agency released its first map. The map paired two incumbent Republicans in one U.S. House district and two incumbent Democrats in another U.S. House district. The map also created 7 potential incumbent versus incumbent combinations in the State Senate elections and seven districts without incumbents. The State House map created 14 vacant districts and 14 potential incumbent versus incumbent races.[19] The Iowa State Senate passed the plan 48 to 1, and the House of Representatives approved the plan 90 to 7.[20]

    The new State House districts varied from the ideal population count by no more than 1.93 percent, or less than a 300-resident deviation from the target for the least accurate district.[21]

    About legislative sessions in Iowa

    The Tenth Amendment of the U.S. Constitution declares that any power not already given to the federal government is reserved to the states and the people.[31] State governments across the country use this authority to hold legislative sessions where a state's elected representatives meet for a period of time to draft and vote on legislation and set state policies on issues such as taxation, education, and government spending. The different types of legislation passed by a legislature may include resolutions, legislatively referred constitutional amendments, and bills that become law.

    The Legislative Department of the Iowa Constitution establishes when the Iowa General Assembly, of which the Senate is a part, is to be in session. Section 2 of the article states that the General Assembly is to convene its regular session on the second Monday of January of each year. The General Assembly can also be called into special session by a proclamation of the Governor of Iowa or by a written request of two-thirds of both houses of the General Assembly.

    Legislative roles and procedures

    Every state legislature throughout the country features its own internal procedures that it uses to govern itself and how it interacts with other parts of state government. Ballotpedia's coverage of internal state legislative procedures includes veto overrides, the role of the legislature in the state budget, procedures for filling membership vacancies, and redistricting.

    Veto overrides

    Veto Override Graphic-No party.png

    See also: Veto overrides in state legislatures

    State legislatures can override governors' vetoes. Depending on the state, this can be done during the regular legislative session, in a special session following the adjournment of the regular session, or during the next legislative session. The rules for legislative overrides of gubernatorial vetoes in Iowa are listed below.

    How many legislators are required to vote for an override? Two-thirds of members in both chambers.

    Two-thirds of members in both chambers must vote to override a veto, which is 67 of the 100 members in the Iowa House of Representatives and 34 of the 50 members in the Iowa State Senate. Iowa is one of 36 states that requires a two-thirds vote from both of its legislative chambers to override a veto.

    How can vetoes be overridden after the legislature has adjourned?

    Vetoes can be overridden in a special session called by the legislature.[32] Two-thirds of members in both chambers must agree to call for a special session.[33]

    Authority: Legislative Department, Section 16 of the Iowa Constitution.

    "Every bill which shall have passed the general assembly, shall, before it becomes a law, be presented to the governor. If he approve, he shall sign it; but if not, he shall return it with his objections, to the house in which it originated, which shall enter the same upon their journal, and proceed to reconsider it; if, after such reconsideration, it again pass both houses, by yeas and nays, by a majority of two thirds of the members of each house, it shall become a law, notwithstanding the governor's objections."

    The state operates on an annual budget cycle. The sequence of key events in the budget process is as follows:[34]

    1. Budget instructions are sent to state agencies between June and July.
    2. Agency requests are submitted to the governor by October 1.
    3. Public hearings are held in December.
    4. The governor submits his or her proposed budget to the Iowa State Legislature by February 1.
    5. The legislature adopts a budget in April or May.
    6. The fiscal year begins in July.

    Iowa is one of 44 states in which the governor has line item veto authority.[34][35]

    The governor is statutorily required to submit a balanced budget. In turn, the legislature is statutorily required to adopt a balanced budget.[34]

    Committees

    See also: List of committees in Iowa state government

    Every state legislature and state legislative chamber in the country contains several legislative committees. These committees are responsible for studying, amending, and voting on legislation before it reaches the floor of a chamber for a full vote. The different types of committees include standing committees, select or special, and joint.

    • Standing committees are generally permanent committees, the names of which sometimes change from session to session.
    • Select or special committees are temporary committees formed to deal with specific issues such as recent legislation, major public policy or proposals, or investigations.
    • Joint committees are committees that feature members of both chambers of a legislature.

    Ballotpedia covers standing and joint committees. The Iowa State Senate has 18 standing committees:


    Constitutional amendments

    In every state but Delaware, voter approval is required to enact a constitutional amendment. In each state, the legislature has a process for referring constitutional amendments before voters. In 18 states, initiated constitutional amendments can be put on the ballot through a signature petition drive. There are also many other types of statewide measures.

    The methods in which the Iowa Constitution can be amended:

    See also: Article X of the Iowa Constitution and Laws governing ballot measures in Iowa

    The Iowa Constitution provides two mechanisms for amending the state's constitution— a legislative process and a state constitutional convention. Iowa requires a simple majority vote (50% plus 1) for voters to approve constitutional amendments.

    Legislature

    See also: Legislatively referred constitutional amendment

    A simple majority vote is required during two successive legislative sessions with an election for state legislators in between for the Iowa State Legislature to place a constitutional amendment on the ballot. That amounts to a minimum of 51 votes in the Iowa House of Representatives and 26 votes in the Iowa State Senate, assuming no vacancies. Amendments do not require the governor's signature to be referred to the ballot.

    Convention

    See also: Convention-referred constitutional amendment

    According to Section 3 of Article X of the Iowa Constitution, a question about whether to hold a state constitutional convention is to automatically appear on the state's ballot every 10 years starting in 1970. Iowa is one of 14 states that provides for an automatic constitutional convention question.

    The table below shows the last and next constitutional convention question election years:
