Clinton does not need to win out at 70% - that is ludicrous. She needs to win over the vast majoriity of the superdelegates. But I would suspect if Obama emerges in June as a flawed GE candidate that the party will nominate Clinton - whether by superdelegate defection to Clinton or otherwise.
If he enters the GE flawed it will be her doing.
Have you actually looked at the numbers she needs to win by? It seems like you haven't.
