Kansas

A dated list of changes to how Americans vote: district maps, polling places and drop boxes, voting laws and rules, and courts and election officials. Each entry says who did what and when, shows what became of it, and links to the page it rests on. Attempts that failed are listed as failed. Entries that rest on a news report name the outlet.

This is the state view: events recorded for Kansas, then national events that apply here. See the national timeline.

    Kansas Reflector reports the 2026 effort to redraw Kansas congressional districts ended without a new map

    Kansas Reflector reported on April 22, 2026 that the Legislature did not redraw the congressional map: "Two-thirds of the state Senate agreed to hold a special session ... but the special session didn't occur because 10 House Republicans declined to sign the petition authorizing the assembly in November. The Legislature could have tackled the issue in the 2026 regular session, but it didn't happen." The report adds that Governor Laura Kelly had said in December it was unlikely a revised map could muster the two-thirds majorities needed to override her veto.

    Kansas House speaker drops effort to call a special session to redraw the congressional map

    KCUR reported that on November 4, 2025, House Speaker Dan Hawkins said his chamber had not gathered enough support to call a planned special session on redistricting. Petitions had circulated since September to redraw the map so it would be harder for Representative Sharice Davids to hold the 3rd District; calling a session without the Governor required two-thirds of each chamber. The Senate had enough signatures, but the effort was about 10 signatures short in the House.

Kobach, following a day-and-a-half bench trial, issued new district lines for the state's congressional seats, the state legislature and the state board of education on June 7, 2012, a little over a month before candidate filing deadlines.

  1. Sep 10, 2026 National Maps and lines Proposed

    Census Bureau proposes residence criteria for the 2030 census that would exclude some noncitizens from the apportionment count

    On September 10, 2026 the Census Bureau, an agency of the Department of Commerce, published a proposed rule in the Federal Register (91 FR 57524, Docket No. 260903-0005, RIN 0607-AA75) that would add two new parts to the Code of Federal Regulations: residence criteria for the decennial census, and standards and restrictions for demographic questions on the census questionnaire. On residence, the notice states that "the Census Bureau proposes to include lawful permanent residents within the apportionment base, while excluding from the apportionment base illegal aliens and aliens whose legal status is less durable and indefinite in length than lawful permanent resident status," and says it is considering using administrative records to determine legal status. The comment period, first set to end October 13, 2026, was extended to November 2, 2026 by a notice published October 5, 2026. Al Jazeera and CNBC reported on the proposal, and CNBC reported that opponents expect litigation.

How this timeline is built

Every entry rests on at least one source that was opened and read, and that source states the date and the fact. Courts, legislatures, election offices, the Justice Department, the Census Bureau, the Federal Register and Congress.gov come first. A news report is used only when no official page states the fact, and it is labeled with the outlet's name. Encyclopedias are not used as sources. History starts in 1965 with the Voting Rights Act. County names come from the Census Bureau's 2024 Gazetteer. Congressional district numbers are those in use for the 2026 election; an event is tagged to a district only when its source names that congressional district.

When a later event changes an earlier one, such as a law later struck down, both entries are listed and point to each other. This page does not predict outcomes or say which party a change helps. U.S. House maps for 2026 · Back to the 2026 voting center.
