The point you are missing is that we are finding out this information because of Operation Chaos.
I could accept that rationale if the masterminds behind OC weren't still running full speed ahead on the Hillary train.
By now, neither Hillary or Obama is going anywhere. If the goal is chaos by keeping her in to the convention, it's been accomplished. She will stay in and continue to attack him.
However, continuing to push OC only strengthens her and increases her chances of winning the nomination more or less fairly and squarely.
She no longer needs Rush's help and yet he continues to give it to her, making it look increasingly like this is about getting her nominated to run against a candidate that Rush has admitted to loathing.
“The point you are missing is that we are finding out this information because of Operation Chaos.”
This same information could have been exposed AFTER Obama had secured the nomination.
