Here’s the story. You can get to the opinion here. The opinion for the 6-3 majority was written by John Paul Stevens and joined by Justice Kennedy and Chief Justice Roberts. Justice Scalia authored a brief concurrence, joined by Justices Thomas and Alito. Both opinions agree that the inconvenience imposed on voters by the law is, generally speaking, minimal. Where they seem to differ is in the view they would have judges take of individual claims of a burden on voting rights. While he rejects the facial challenge offered in this case, Justice Stevens is open to arguments by individuals who assert unreasonable burdens. Scalia’s position is less accommodating.
Update: Beginning in Chicago, John Fund connects the dots contrasting John Paul Stevens (the real reformer), Barack Obama (the faux reformer), ACORN (Obama’s erstwhile client and fellow amicus in this case), the FEC commissioner in waiting Hans von Spakovsky, and John McCain. Oh what a tangled web!
