The lone grain of truth against Section 4 of the VRA was that the situation has changed from the time it was passed until today. BUT, this does NOT in any way, shape or form mean that racism and voter discrimination has somehow disappeared. Instead, it has spread all over the country. And the instances are too numerous to count. In Ohio. And Florida. And Texas. And Arizona. And in many other states.
The best way to reinstate Section 4 is to do it for all 50 states. Every state, county, parish, borough, and city should have to comply with a reinstated Section 4. That way, racists in the South can't complain that they are being singled out, and racists outside the South can have some of their powers checked. No opt-out. No sunshine clause. The only way out is to revisit the law many years later. It's a win for everyone except the Republicans racists.
