Bill Clinton's Global Reach Would Have Pluses and Minuses for a Secretary of State Hillary Clinton

I'm curious to know why they think Hillary would be a good Secretary of State? Wouldn't she be better at DoJ? She doesn't seem to bring much to the table Diplomacy wise and then also seems to have a lot of other problems starting with her husband. Also in Chicago last week was John Kerry who has also been mentioned in the Secretary of State running. If I were advising Obama, I'd reward Sen. Lugar. Even though he's on the other side of the aisle, he has been good to Obama. Also he's got some experience, connections, and would be more of a straight shooter.
