At year’s end, Vice President Kamala Harris is making the rounds of syrupy and supportive interviews, but you can still wonder which of her communications staffers is going to quit after aerobically trying to prepare her for these softball sessions. Molly Jong-Fast was an eager booster at Vanity Fair magazine, begging her to “walk me through” the powder-puff points, but when she told the vice president her mother was the feminist sex-novel author Erica Jong, Harris said “That’s your mom? Nobody tells me anything around here!” Heads will roll.
