Who Sets The Rules
The clause determines whether voting rules — such as ID requirements, mail ballot deadlines and voter roll maintenance — are decided in state capitals or in Washington.
In plain English
Who sets the rules for federal elections.
States generally write the rules for how federal elections are run, but Congress can step in and change those rules.
Simple example
The clause is central to legal challenges over President Trump's March 2025 executive order on mail-in ballots and voter rolls, which critics argue intrudes on state authority over election administration.
Why it matters
What the term actually changes.
Federalism In Elections
It shapes long-running disputes over the balance between national uniformity and state-by-state variation in how Americans vote.
How it works
The mechanics, in practice.
State Default Authority
States pass laws governing voter registration, polling hours, ballot design and mail voting procedures for federal contests, administered by state and local election officials.
Congressional Override
Congress can enact laws altering state rules for federal elections, as it has done through statutes like the National Voter Registration Act and the Help America Vote Act. Executive branch actions in this area are often tested in court.
