What mechanism did the Voting Rights Act use to prevent discriminatory changes in election laws?

• A. Private litigation only
• B. State oversight of elections
• C. No oversight of election changes
• D. Federal oversight and preclearance of elections

Answer: (D)

Federal oversight with preclearance is the mechanism the Voting Rights Act used to prevent discriminatory changes in election laws. Covered jurisdictions with a history of voting discrimination had to obtain approval from the Department of Justice or a federal court before implementing any changes to voting procedures, such as redistricting, registration rules, or polling places. This upfront review stops a change from going into effect if it would dilute or disenfranchise minority voters, ensuring that modifications are reviewed for potential discriminatory impact.

This approach goes beyond relying on private lawsuits or leaving changes unreviewed; it actively vetoes or conditions changes before they occur. For context, the enforcement framework also included challenges under Section 2, but the preclearance requirement was the key preventive tool. Note that the effectiveness of preclearance depended on the coverage formula, which the Supreme Court later limited in Shelby County v. Holder, reducing the jurisdictions subject to preclearance until Congress updates the formula.
