It may have been cute the first day he said it, but with Hillary Clinton's spiraling poll numbers and increasing calls for her to get out of the race, I suspect the last thing she needs is James Carville continuing to run around and call Bill Richardson "Judas," let alone write a full blown piece about it in the Washington Post.
It's just another reminder of the ugliness of the Clinton machine, and it could hardly come at a worse time for Hillary.
