 Journalists who write books about living first ladies based upon interviews with those who knew them are an important interpretive first wave and very useful for scholars. I'm thinking here of Carl Bernstein on Hillary Clinton, Ronald Kessler on Laura Bush, Peter Slevin on Michelle Obama, for example. Susan Page interviewed Barbara Bush and Darlene Superville interviewed Jill Biden for their books. But first ladies often seem to decline interviews, especially when they have their own memoirs to pen.
