Who will replace Hillary Clinton as Secretary of State?

Hillary Clinton will be resigning from her post as Secretary of State. Who will replace her? There is a lot of buzz about Susan Rice, the United States Ambassador to the United Nations. Some think that Obama will make her Secretary of State. However, many people, Republicans especially, are against this because of her report on the Benghazi attack. She said it happened because of anti-Islam video that an American put out. Obama defended her and people are wondering, "Will Obama go ahead and make Rice Secretary of State even though so many are opposed to this?"
