Apologies for the micro diary but this is all I've found as SCOTUS literally just issued its ruling on the Voting Rights Act minutes ago.
TPM:
SCOTUS Strikes Down Section 4 Of Voting Rights Act
NYT:
Supreme Court Strikes Down Part of Voting Rights Act
The Supreme Court on Tuesday morning announced a ruling on the constitutionality of part of the Voting Rights Act of 1965, which requires nine states, mostly in the South, to obtain federal permission before changing voting procedures. Legal analysts were reading the decision to understand its scope and consequences.
Awaiting more substantive diaries and analysis from the experts around here.
