It is obvious that neither Clinton nor Obama will go into the Convention with a workable majority of delegates.
According to CNN Election Central this morning, Clinton has 1108 (885 pledged plus 223 superdelegates) and Obama has 1049 (918 pledged plus 131 superdelegates).
The 26 Edwards delegates could become important. The superdelegates may have to decide which candidate is electable.

The stage is being set for a long and bitter Democratic Convention.
