As Congress continues to probe the attacks on the U.S. Consulate in Benghazi, Libya, the conversation seems to be gradually shifting from a hothouse hunt for the scalp of U.N. Ambassador Susan Rice to larger questions about the security breakdown itself. Buzzfeed's John Stanton sussed out that a shift seemed imminent at the end of last week, and while Sunday's political talk shows featured Rice's betes-noires -- Sens. John McCain and Lindsey Graham -- there was a sense that cooler heads were taking over. Most notably, McCain amigo Sen. Joe Lieberman made it clear to Fox News' Chris Wallace that he wasn't all that interested in pursuing the Susan Rice agita much further.
