Early reports are that the Supreme Court is again concerned about standing in the DOMA case. Roberts in particular noted that it was unusual for the executive branch to choose not to defend a law passed by Congress.
So again, SCOTUS seems wary about even deciding the case.
UPDATE:
Final update: #scotus 80% likely to strike down #doma. J Kennedy suggests it violates states’ rights; 4 other Justices see as gay rights.
