The day Justice John Paul Stevens announced his retirement, Senate Republican leadership vowed to obstruct the confirmation of whoever was nominated to replace him. Today, Republican Senators who had previously praised nominee Elena Kagan’s intellect and qualifications have become strikingly less supportive.

And now we have evidence that the obstruction of Obama’s Supreme Court pick, as a way of delaying progress on policy initiatives like climate change regulation and immigration reform, has been the GOP’s explicit strategy all along.

Talking Points Memo’s Brian Beutler obtained a recording of an April 22 RNC strategy call led by right-wing activist Curt Levey:

The crux of the GOP’s strategy is to use Obama’s nominee to wedge vulnerable Democratic senators away from the party, and drag the confirmation fight out until the August congressional recess, to eat up precious time Democrats need to round out their agenda.

“[I]t wouldn’t take much GOP resistance to push a final vote into early August,” Levey advised. “And, look, the closer we could get it to the election, frankly, the better. It would be great if we could push it past the August recess because that forces the red and purple state Democrats to have to go home and face their constituents.”

Levey acknowledged that a filibuster likely won’t last–that Obama’s nominee, now known to be Solicitor General Elena Kagan, will almost certainly be confirmed. But he hammered home the point to Republicans that there’s value in mischaracterizing any nominee, and dragging the fight out as long as possible, whether or not Obama’s choice is particularly liberal.

This is frustrating, but not surprising, from a party that has recently displayed an unparalleled mastery of the Senate’s rules for delay. If they’re willing to stall the confirmation of one of their own party’s most prominent spokespeople, why would they not draw out the confirmation process for an obviously qualified Supreme Court nominee?
