Karen phrased it about as tactfully as she could, but she did just ask Edwards, “Can voters trust you to be in it for the duration?” To which Edwards replied, “We’re in it for the duration.”
A more important response came later, when he pointed out that he and Elizabeth are lucky: “A lot women who have cancer don’t have a choice. A lot of women who have cancer get the diagnosis have to get up and go to work the next day.” [paraphrasing] I suspect that this reply will be in heavy rotation for a good while. Perhaps “the duration.”
