The Voting Rights Act has been gutted, allowing southern states to gerrymander and reduce the voting power of minorities. Not even hypothetically, Texas did so moments after the Supreme Court gutted the VRA.

States are aggressively attacking minority voting rights through several angles - reducing sites you can vote and hours you can vote at them, especially in minority areas, ID requirements that hurt people who don't own cars and thus don't need Drivers' Licenses (and are essentially a form of poll tax), and many other nefarious tactics.
