I have written about her in 42 columns since Sen. John McCain picked her as his presidential running mate in 2008. I’ve mentioned her in dozens more blog posts, Web chats, and TV and radio appearances. I feel powerless to control my obsession, even though it cheapens and demeans me.

But today is the first day of the rest of my life. And so, I hereby pledge that, beginning on Feb 1, 2011, I will not mention Sarah Palin – in print, online or on television – for one month. Furthermore, I call on others in the news media to join me in this pledge of a Palin-free February. With enough support, I believe we may even be able to extend the moratorium beyond one month, but we are up against a powerful compulsion, and we must take this struggle day by day.
