Riiiight!!! And because a republican senator won't overrule a democrat President's choice, no matter how liberal, biased, or unqualified, he expects that, if and when the situation is reversed, democrats will return the favor. Tell that to Robert Bork!
Tell that to Miguel Estrada - who, by the way, was FAR more qualified for the position that he was nominated, than Sotomeyor will ever be for SCOTUS.
