Today's edition of quick hits:
* Another shooting: "A gunman killed three people Friday in central Pennsylvania, including a woman in a church, before police shot him dead, authorities said. Three state troopers were injured, including one who was shot twice in the chest but survived thanks to his bulletproof vest."
* President Obama eulogized Daniel Inouye today at a memorial service at the National Cathedral, calling the Hawaiian hero his "earliest political inspiration." Obama added, "May God bless Daniel Inouye and may God grant us more souls like his."
* Syria's Assad regime has begun using cluster bombs, punishing rebels and civilians alike.
* Republican opposition to a pending farm bill is likely to cause a sharp spike in milk prices in January.
* John Kerry's Secretary of State nomination is already generating Republican support, reinforcing the perception that he'll be confirmed easily.
* Chuck Hagel's prospective nomination as Defense Secretary isn't going as well. Sen. John Cornyn (R-Texas) is the latest Republican senator to condemn his former Republican colleague, saying Hagel's views are "outside the mainstream."
* In related news, Hagel today retracted "insensitive" anti-gay comments he made in 1998 about James Hormel's nomination to be ambassador to Luxembourg, adding, "I apologize to Ambassador Hormel and any LGBT Americans who may question my commitment to their civil rights." For his part, Hormel found Hagel's apology underwhelming and opportunistic.
* A long-shot lawsuit challenging the constitutionality of Senate filibuster rules was dismissed by a federal judge yesterday on procedural grounds.
* Someone probably ought to let the NRA know that Columbine had an armed guard.
* Add Sen. Bob Casey (D-Penn.) to the list of centrist Democrats who've changed their perspective on guns laws in the wake of the Sandy Hook Elementary massacre.
* And Rush Limbaugh briefly argued today that mass shooters "are all liberals," before taking it back. Classy.
