The voting rights act was a recognition that there's something wrong if a state with 10 congressional representatives and 30% black population ends up with only 1 or even 0 black representatives. That was often done by drawing districts such that the 30% of black voters are diluted by the 70% white voters.

The supreme court has called this "racial gerrymandering" which is a bit rich considering they previously ruled that gerrymandering itself was just fine. Apparently, only fine when it has partisan benefits.

Either way, the solution here is a tool not available when the VRA was passed, and that's fair ungerrymandered maps. There are tons of algorithms that produce fair maps, certainly much more fair maps vs the current gerrymandered maps. We even have algorithms that can measure the level of gerrymandering.

An anti-gerrymandering bill would be good for everyone and should be supported at the federal level. The only people it's not good for is incumbents.
