Super rollout

Josh Marshall at TPM describes why he doesn't believe Obama has had or does have superdelegates "banked" for orchestrated rollout.  His reasons make sense. But this graph is why I believe they've been in the bank and unrolled in an orchestrated way by the Obama campaign.  You can't convince me that the supers would just happen to endorse in such a uniform pattern (3-4 per day since May 7) left to their own devices.  And the reason he needs to control rollout is to avoid the headline and impression that the election was handed to him by the supers, though of course their votes were necessary to secure the nomination (in spite of having the majority of pledged delegates).
