She cannot overturn Osama's sorry, Obama's lead in votes and ordinary delegates. The superdelegates have made it clear whom they consider to be the more popular candidate. But she persists.
She knows the future and it holds very little for Obama after a set date. I choose not to know the date. It may not succeed. The hot tip on the WWW is that it will have a very strong UK connection. Maybe. We all know how accurate "internet chatter" can be!
As the only candidate left who has so many delegates, she will be favoured over Edwards.
These controls are said to be necessary in a democracy. You can't trust the voters.
