In a discussion at another site I go to someone made an interesting claim I'd never seen before that a large part of the reason the Democrats struggle with gerrymandered seats is not simply because of Republican-led gerrymandering but because of the requirement for majority/minority districts set in the Voting Rights Act. This creates districts that are packed with lots of wasted Democrat votes.
I don't know too much about this topic, is there any truth in that?
PS is district the right word for American constituencies?
