This DNC not being able to give 100% is a MUCH bigger problem than anyone acknowledges. This is NOT a defeat for Clinton. This is what Clinton wants!!! If the DNC seats 100% then she has no more reason to stay in the race (once he crosses the threshold.)
If it is true that the DNC rules require a punishment and any punishment is upheld or appended, it gives Clinton her raison d'etre. If the only way to get the delegates fully, 100% seated is to change the rules there is only one way that those rules can be changed...By a vote at the convention.
Anything shy of 100% gives her the reason to stay in until the convention. Even if enough Supers come over to push him over the 2200+ number, she will stay in, citing the civil rights of these folks.
She will position herself as the champion of the disenfranchised and hope that "anything can happen".
This is my understanding of the process. Please correct me if I'm wrong.
