On the CBS Evening News tonight, Mike Huckabee used the president’s commutation of Scooter Libby’s sentence to deflect Mitt Romney’s criticism of Huckabee’s pardon record (which included letting 12 murderers go). Here’s a rough transcript:

NANCY CORDES: Until now, Huckabee has tried to deflect attacks from his opponents on issues ranging from crime to illegal immigration, but today he signaled he’s ready to fire back.
GOV. HUCKABEE: Mr. Romney has commended President Bush for the pardon of Scooter Libby.
CORDES: [He’s] Criticizing Mitt Romney for refusing to pardon a decorated Iraq war vet whose arrest for firing a b.b. gun when he was 13 makes him ineligible to become a police officer.
HUCKABEE: How do you justify not giving that kid a pardon but Scooter Libby gets one?
