Utah’s Court-Ordered Redistricting: Where Things Stand

By EditorMay 22, 20260 Comments

The Utah congressional map controversy continues into 2026. On November 10, 2025, a state trial court invalidated the Utah legislature's congressional map on the grounds that it violated the anti-partisan gerrymandering rules enacted under Proposition 4, which voters approved seven years ago. The court adopted a remedial map submitted by the plaintiffs in the case (The Utah League of Women Voters and the Mormon Women for Ethical Government) to be used in the 2026 mid-term election. That map created three Republican-leaning districts and one Democratic-leaning district centered on Salt Lake County. In response, the Utah Legislature launched an aggressive multi-front…

SCOTUS Reverses Mississippi Legislative Map Ruling

By EditorMay 18, 20260 Comments

The U.S. Supreme Court, in a brief order Monday, reversed a lower court's ruling that determined Mississippi lawmakers unlawfully diluted Black voting strength when it redrew the state's legislative districts. The Supreme Court's decision to toss out the ruling in the Mississippi case, along with a similar ruling in North Dakota, is the latest order set off by the justices' 6-3 decision in Callais last month. Earlier this month, the high court similarly tossed a Voting Rights Act (VRA) ruling against Alabama's congressional map that had mandated the state have two majority-Black districts. The Callais ruling, along with subsequent orders…

Why the 2030 Census LUCA Program Matters to Redistricting and GIS Staff

By EditorMay 16, 20260 Comments

Most redistricting discussions focus on the maps, who draws them, what criteria they must meet, and how they will hold up in court. But every redistricting map built from 2030 Census data will ultimately rest on a foundation that GIS and redistricting staff rarely talk about: the Census Bureau's residential address list. The Local Update of Census Addresses operation is the first to occur in every decennial census cycle, and it gives state, tribal, and local governments their only opportunity to directly help ensure an accurate enumeration by reviewing and submitting updates or corrections to the confidential address list before…

What Local Officials Need to Know about the Recent U.S. Supreme Court Voting Rights Act Decision

By EditorMay 15, 20260 Comments

Section 2 of the Voting Rights Act of 1965 is the federal law that has most directly shaped how local governments draw their district maps and structure their elections. It is a permanent, nationwide prohibition on any voting standard, practice, or procedure that results in the denial or abridgment of the right of any citizen to vote on account of race, color, or membership in a language minority group. The Act applies to every level of government, including county commissions, city councils, school boards, and judicial districts. In practice, the law has been most often invoked at the local level.…

South Carolina Governor Calls Special Session on Redistricting After Senate Blocks Extension

By EditorMay 14, 20260 Comments

South Carolina Gov. Henry McMaster called a special session Thursday evening for state lawmakers to tackle redistricting ahead of the midterm elections, announcing on X: "I have issued an Executive Order calling the General Assembly back for an extra legislative session to address the state budget and congressional districts." The session is set to begin on Friday morning. McMaster initially chose not to set a special session but changed course after the Republican-led state Senate rejected a measure to extend its current session to take up a redrawn map, despite pressure from President Donald Trump, who posted on Truth Social,…

Georgia Governor Calls for June Special Session for Mid-Decade Redistricting

By EditorMay 14, 20260 Comments

Georgia Gov. Brian Kemp has called the General Assembly into a special session beginning June 17 to consider new congressional, state Senate, and state House district maps for the 2028 election cycle, according to the governor’s May 13 proclamation. The session is being called in response to the U.S. Supreme Court’s April 29 decision in Louisiana v. Callais, which affected how race may be considered in redistricting. The proposed maps are not expected to govern this year’s midterm elections because the proclamation specifies the 2028 cycle. Kemp noted that it was too late to change the maps before the upcoming…

What Is a Shapefile and Why Do You Need One for Redistricting?

By EditorMay 14, 20260 Comments

If you have spent any time around redistricting software or GIS professionals, you have probably heard the term "shapefile" and possibly nodded along without knowing what it means. A shapefile is a digital file format that stores the geographic boundaries of a defined area as a map layer. Think of it as the outline of a jurisdiction, your city limits, your county boundaries, your voting precincts, your census tracts, all saved in a format that mapping software can read, display, and analyze. TIGER boundary files are shapefiles from the Census Bureau that are important for drawing legally compliant district maps.…

Missouri State Supreme Court Hears Oral Argument in 3 Challenges to 2025 Congressional Map

By EditorMay 12, 20260 Comments

The Missouri Supreme Court heard oral arguments Tuesday morning in three consolidated challenges to the state's new congressional map, known as the Missouri First Map, which Gov. Mike Kehoe signed into law following a special legislative session in September 2025. The map, drawn as part of President Trump's broader mid-decade redistricting push to secure additional Republican congressional seats ahead of the 2026 midterms, splits parts of Kansas City into three districts and adds Republican-leaning areas to the district of Rep. Emanuel Cleaver, one of the state's two Democratic House members. The Republican-led legislature passed the map last fall, targeting one…

With Election Clock Ticking, Virginia Democrats File Emergency SCOTUS Appeal

By EditorMay 11, 20260 Comments

Virginia Democrats on Monday asked the U.S. Supreme Court to revive the voter-approved redistricting amendment struck down last week by the Supreme Court of Virginia, escalating the fight over the state's congressional map to the nation's highest court. In an emergency application filed with Chief Justice John Roberts, attorneys representing House Speaker Don Scott, Senate Majority Leader Scott Surovell, Senate President Pro Tempore Louise Lucas, and the commonwealth of Virginia asked the court to pause the state ruling while the appeal moves forward. Democrats are asking the court to immediately freeze the Virginia ruling and keep the new congressional maps…
