SCOTUS says places with histories of violating the voting rights of minorities are now free to continue doing so.
More specifically, they chucked out section 4 which determined which areas needed pre-clearance for changes to voting laws under section 5 of the Voter Rights Act. Congress could fix it (well, probably they couldn't even if they wanted to), and monkeys could fly out of my butt, so section 5 is essentially dead.
