In my library I have three copies of books on Hillary Clinton long before she declared her intention to seek the Democratic nomination for President.
The First Partner by Joyce Milton (1999)
Hillary's Choice by Gail Sheehy (1999)
Living History: A Memoir HRC (2003)
A cursory glance at Amazon brings up:
It Takes a Village HRC
A Woman in Charge by Carl Bernstein
Leadership Secrets by Rebecca Shambaugh
Hillary Clinton: Her Way by Jeff Gerth
Target: Caught in the Crosshairs of Bill and Hillary by Kathleen Wiley
The Case for Hillary Clinton by Susan Estrich
Hillary Clinton: An American Journey by Laura Driscoll
The Case Against Hillary Clinton by Peggy Noonan
Notes from the Cracked Ceiling by Anne E. Kornblut
Hillary Clinton: The Inside Story (yawn) by Judith Warner
Madam President by Suzanne Goldenberg
Hillary Clinton's Race for the White House by Regina Lawrence
Female Force by Neal Bailey
American Evita by Christopher Andersen
Hillary Clinton by Dena Levy
Almost Madam President by Nichola Dutgold
Political Power by Laura Guzzo
Can She Be Stopped by John Podhoretz
and a half dozen more but you get the drift....but by any stretch of the imagination this is a lot of books, possibly more books on a single politician than anyone else, save those comics from North Korea.
I think it was in Sheehy's book where I read towards the end a homily along the lines of "What do Bill and Hillary have in common? The answer is that they both love Bill."
Hillary has been outstanding Secretary of State at the State Department; it has taken its toll on her and I would be surprised if she stuck around for a second term with Obama.
