Okay, this is interesting. I’ve just learned that CNN has told top Dem strategists James Carville, Paul Begala, and Robert Zimmerman — who are CNN mainstays but are all Hillary supporters — that they will not be doing any more political analysis on the network until the Democratic primary has reached a conclusion.

I’m also told that this move came after the Obama campaign repeatedly complained to high level officials at CNN about the presence of Carville and Begala on the network.

After I reached him today and pointed out that he hadn’t been on CNN in some time, Carville confirmed to me that the network had told him that he wouldn’t appear until the Dem primary is resolved.

Sam Feist, CNN’s political director, also confirmed the decision to me. “As we got closer to the voting, we made a decision to make sure that all the analysts that are on are non-aligned,” Feist said, adding that the decision had been made around the start of December. “Carville and Begala are two of the best analysts around and we look forward to seeing them on CNN plenty of times in the future, once the nominating process has ended.”

Though there are plenty of other contributors on all of the networks who are less than objective this is probably a decent move by CNN.
