Who do you think Zero will replace on the SCOTUS bench? Some conservative? Look at his other picks you want him to have two more? What is your agenda?
The danger is the Romney picks, not Obama replacing the liberal Ginsburg with another liberal, and remember Clinton did not appoint a single SC justice in his second term.
Romney will give the SC a liberal majority for 40 years or more and it will be the fault of all who voted party over principle. Romney is a liberal and he will seal the deal for the liberals who will have finally won by having a fake conservative picking the judges..
