The Supreme Court did not take away the rights of Black voters. Rather it supported the VRA as our democratic institutions passed it.
Don't like what the VRA says? GREAT! That's why we have lawmakers to make better law. We should stop reelecting the congresspeople who failed to improve the law.
The Brennan Center can also write about the world being flat. So what? We can read the opinion for ourselves to see what it did, and we can see for ourselves that any such outfit putting out such nonsense seems to be just trying to claim headlines and/or score political points.
After all, that's reasonable marketing for them.
Look at what the SCOTUS ruling actually said, not what some thinktank tells you they said.
