Looking through the data, It seems the Hillary theory is this.. Unlike the Pledged Delegates, the Super Delegates position do not matter until the convention, whereas the pledged are firmly in place based upon the states rules.
She sees FL and MI as a big boost to her pledged delegate numbers. A big enough boost to put her within striking range of the nomination. All she needs are more Super Delegates. <<IF>> she is holding back an "October Surprise" for Obama, that just might do it.
All the talk about "The Super Delegates need to step in and stop Hillary!!!!11!!!1" at DU and other places is just talk. There is nothing they can do until they actually vote at the convention. -- This is why Hillary (and Operation Chaos) moves on.
