We don’t know who the next Supreme Court nominee will be, but Senate Republicans are already vowing to put up a fight.

Senate minority leader Mitch McConnell issued a statement this morning wishing retiring Justice John Paul Stevens well and warning that whoever is nominated to replace him won’t get off easy:

As we await the President’s nominee to replace Justice Stevens at the end of his term, Americans can expect Senate Republicans to make a sustained and vigorous case for judicial restraint and the fundamental importance of an even-handed reading of the law.

We respect the judicial confirmation process, but shouldn’t Republicans see who they’ll be considering before they promise “sustained and vigorous” opposition? Or are they having so much fun holding up nominations that it doesn’t really matter?
