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.

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.
