Her freeper admirers forget - or perhaps never heard - that there are those who've long criticized Noonan for breaking the speechwriters' code of anonymity by announcing that she wrote Reagan's words. By playing up the role of the speechwriter, it's been argued, she played into the hands of liberals who once claimed Reagan always had to be given a script. A lot of people once resented her for her self-promotion, but maybe because it's been so successful, those who resent it now keep their lips buttoned.
I wouldn't worry too much about it. Others know that Reagan was his own best speechwriter.
Besides, Reagan's desktop plaque said something about how "There's no limit to how high a man can go as long as he doesn't care who gets the credit." Reagan could care less if his critics believed he was merely an actor who only delivered lines given to him in a script. Others know better.
Peggy was not the first presidential speechwriter to "break the code of silence" and write about her work. Schlessinger wrote about his work with Kennedy. Bill Safire wrote a great book about being a Nixon speechwriter (titled "Before the Fall"). Peggy definitely wasn't the first. She was, however, the funniest and most enjoyable to read IMHO.
