It’s definitely a legitimate concern. However, *now* Romney has said in debates that he will appoint Alito, Scalia, Roberts, Thomas types.
With a tea party Senate, we can hold him to that.
It won’t work that way. There will be enough democrats and rinos to push any nominee through. Without 60% control by conservatives, moderate/libertarian/unknown nominees will get through.
There is no way they will achieve 60% conservative senators, since they’re supporting all of the retreads with the exception of Lugar and maybe Hatch.
