Good article over at the New York Times on the possibility of Barack Obama bringing Hillary Clinton into his cabinet. There are a lot of comparisons to Lincoln's cabinet, but perhaps Lincoln's cabinet wasn't as great as it we are told it is.
I would say bringing your competitors into your cabinet is probably a good way of neutralizing them, and I would guess that is what Obama is trying to do here. Not that Clinton wouldn't make a good Secretary of State, but I think Obama also wants her on his side.
