US SB2523

Revises the Voting Rights Act of 1965 preclearance formula, requiring states with 15+ voting rights violations in the past 25 years (or 10+ with at least one by the state itself) and political subdivisions with 3+ violations to obtain federal approval before implementing voting changes

Establishes "practice-based preclearance" requiring federal review of specific voting changes in jurisdictions meeting demographic thresholds, including changes to election methods, redistricting, voter ID requirements, multilingual voting materials, and polling place locations

Strengthens Section 2 vote dilution and denial claims by codifying legal standards from Thornburg v. Gingles, establishing criteria for proving discriminatory burden, and prohibiting voting changes that diminish minority voters' ability to elect preferred candidates (retroactive to January 1, 2021)

Creates new transparency requirements mandating public notice of voting procedure changes within 48 hours, polling place resource allocation 30 days before elections, and demographic/electoral data for redistricting changes

Adds criminal penalties (up to $5,000 fine and 1 year imprisonment) for interfering with or intimidating voters, poll watchers, election officials, or election workers through force or threats, and for damaging polling places or election infrastructure
