The best example of recent years, inevitably, is Barack Obama, who wrote not one but two such efforts. In the first, Dreams from My Father — a surprisingly candid memoir — he told the public about himself. In the second, The Audacity of Hope — more of a policy prescription — he told people what he would do were he in charge.
Eamon Gilmore, in his book, does neither. Or at least, not in any great detail.
