See this Wall Street Journal oped (paid subscription required). A snippet: “The reapportionment decisions are now what Sen. Specter calls ‘super-precedents’: There is literally zero chance that the court will revisit population equality in legislative districts. Judge Alito himself has called one person, one vote a ‘bedrock principle.’ But the unfinished business of the apportionment cases remains unfinished. No one should profess shock or horror if, in 1985, Samuel Alito joined Justices Frankfurter and Harlan — and might today express the concerns of Justice Thomas over race-based districting.” My own views on this topic are here.
