Well, Ferraro did mention the "luck" factor, and it's still working. Both Michigan and Florida, where Hillary probably would have done well early on, are on ice, and as soon as Hillary gained some momentum in Texas and Ohio, it's back to Mississippis for an almost all black primary.
                               Couple that with a generation of up-scale Democratic baby-boomers who were taught to feel guilty about the racial make up of America, and huge numbers of college students who dominate much of the caucuses, and you've got a mixture that leap-frogs Obama to the top.
                               The larger problem is, none of that is likely to help him in the general election.
