There's no need for conservatives to hear President Obama's nominee for the Supreme Court. They object already. The New York Times reports:
"Preparing to oppose the confirmation of Mr. Obama's eventual choice to succeed Justice David H. Souter, who is retiring, conservative groups are working together to stockpile ammunition. Ten memorandums summarizing their research ... dissect possible nominees' records, noting statements the groups find objectionable on issues like abortion, same-sex marriage, the separation of church and state and the propriety of citing foreign law in interpreting the Constitution. While conservatives say they know they have little chance of defeating Mr. Obama's choice because Democrats control the Senate, they say they hope to mount a fight that could help refill depleted coffers and galvanize a movement demoralized by Republican electoral defeats."
In other words, howl about wedge issues in the hopes of ginning up the base and raising money. If we were social conservatives, we'd feel used.
