Book excerpt: In a natural follow-up to her national bestseller Front Row at the White House, the dean of the White House press corps presents a vivid and personal presidential chronicle. Currently a columnist for Hearst and a former White House bureau chief for UPI, Helen Thomas has covered an unprecedented nine presidential administrations, endearing herself with her trademark "Thank you, Mr. President," at the conclusion of White House press conferences. Thomas has amassed many wonderful tales about her personal interactions with and observations of the presidents and their families that can all be found in Thanks for the Memories, Mr. President. In nine riveting chapters -- one for each administration -- Thomas delights, informs, spins yarns, and offers opinions on the commanders in chief, from Kennedy through George W. Bush. In these accounts, Thomas reveals Kennedy's love of sparring with the press, the unique invitation LBJ extended to Hubert Humphrey to become his running mate, and Reagan's down-home ways of avoiding the press's tougher questions. This book is as entertaining and compelling as Helen Thomas herself.
