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 Utah, then national events that apply here. See the national timeline.

  1. Nov 10, 2025 Congressional district: UT-1 Maps and lines Decided by a court

    Judge Gibson rejects the Legislature's Map C and orders the plaintiffs' Map 1 for 2026

    In a ruling and order dated November 10, 2025 in League of Women Voters of Utah v. Utah State Legislature (Third District Court, No. 220901712), Judge Dianna Gibson found that the Legislature's remedial congressional map, "Map C" enacted in S.B. 1012, "does not comply with Utah law," that it was "drawn with partisan political data on display," and that it was "drawn with the purpose to favor Republicans." She granted a preliminary injunction against enforcing S.B. 1011 and S.B. 1012 and adopted the plaintiffs' "Map 1" for Utah's congressional elections. KUER reported that Map 1 creates a district centered on Salt Lake County.

    The Utah Supreme Court wrote that during the 2020 General Session the Legislature passed Senate Bill 200, which repealed the voter-enacted initiative and replaced it with a new law. The plaintiffs in the later suit alleged that S.B. 200 removed "the ban on partisan gerrymandering" for maps the Legislature creates and weakened the independent commission's role.

  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.
