They can’t help themselves. Here’s Clinton surrogate Robert Johnson:
"I am frankly insulted that the Obama campaign would imply that we are so stupid that we would think Hillary and Bill Clinton who have been deeply and emotionally involved in black issues when Barack Obama was doing something in the neighborhood that I won’t say what he was doing but he said it in his book."
I guess they’ve been told not to use the "cocaine" word any longer, but code will work just as well.
