You're dreaming. Name Republican senator who would vote against the most moderate judge Bush would nominate (Gonzales for example)? Not one would.
However I think there has been way too much preemptive weeping and wailing about this. Bush's appellate court appointments have been excellent. There is no reason to think his SCOTUS appointments won't be also, despite what Bill Krystol says.
For most of us, this is yet more evidence that the President will keep his promise to nominate Justices who respect the Constitution and are not activist lawmakers in robes.
For the Bush-hating wingnuts, this is just another excuse to bash the President simply because they don't like his positions on other issues such as immigation or spending.
The President never promised to close the borders and kick all the illegals out. He did promise to nominate conservative judges. He has kept his promises as President, and he will do so again.
The wingnuts are willing to assume the worst before a nominee is even announced. Aty least the French don't surrender until the Germans beat them on the battlefield. The wingnuts will surrender before a shot is fired. Fortunately, success does not depend on these noisy but ultimately irrelevant whiners.
