It seems pretty clear the DBM wants to BE the selector of nominees.
They don’t want the public to realize that conventions are SUPPOSED to select the nominee.
If conventions select the nominee then the DRM (cnn,fnc,pmsnbc) are just reporting observation rather than making news.
Hillar is polling 20 points ahead in a state where Obama should be now ahead after a being ahead.
The DBM is not asking the questions about the convention and if Obama has the gravitas to “close the deal”.
