Justice Ginsburg might go for that option, She’s often expressed concern that Roe was badly decided and created more problems than it solved while agreeing personally with the outcome.
It is not our job to protect the people from the consequences of their political choices . This is BJ Clinton's law and it stands until Congress passes a law to change it.
Shouldn't it simply allow the original ruling by the California SC to stand? If it is a state issue then that ruling by the state's highest court should decide it for that particular state. McConnell is having it both ways still, that is homosexuals get everything they want - overturning the voters vote for Prop. 8 and undoing DOMA.
