She won't drop out till after she humiliates him in Kentucky and West Virginia. I expect she'll continue to push for Florida and Michigan to be seated. I am still amazed the Democrat party doesn't care that only 48 states will be represented at their convention after all the hubub about counting every vote in 2000.
Eh...like Dr. Dean says, there are conflicting principles here: being fair to the voters, who aren't to blame for their politicians not following the rules, and being fair to the candidates, who didn't campaign in the states out of respect for the DNC's ruling that these states won't count. There will be a compromise. FL/MI will be seated somewhere between the results of the primary and the 50/50 Barack would like to see, in some way or shape. I personally am fond of seating both their delegations as half-delegates like Guam and Samoa, and reinstating their supers. We'll see...but FL/MI won't change the final outcome.
