Standing Firm by Dan Quayle.
I recommend this to go back and read, even if you have not done so. Quayle mis-read some people, and unfortunately the record is there in black and white. I supported Quayle before he withdrew from the presidential race, and I have no axe to grind. This is an instructive book on how one's opinion of leaders is shaped by events.
Barbara Bush: A Memoir by Barbara Bush.
This is an easy read, but it has some interesting detail, and should be read in preparation for Reflections, by Barbara Bush, which is coming out in October. Reflections will cover the time since they left the White House until their son was elected. Coincidentally, those years are the Clinton years, and advance word is that Mrs. Bush is pulling no punches. Heheheh.
