NEW YORK ( TheStreet) - Sarah Palin won't seek the 2012 Republican presidential nomination. The former governor of Alaska made the announcement during an appearance on the Mark Levin show, a conservative talk radio program. In a letter to her supporters, Palin said she felt the decision reflected what is best for her family, but also that she felt she would be "more effective in a decisive role to help elect other true public servants to office." As for the part she expects to play in the upcoming elections, Palin said that in the coming weeks she will "help coordinate strategies to assist in replacing the President, re-taking the Senate, and maintaining the House." Prior to the announcement, Palin's stance on her potential candidacy was hazy. The one-time vice presidential nominee turned political commentator and reality television star sent mixed signals about taking a backseat role in the 2012 presidential race during a highly publicized appearance in Iowa over Labor Day weekend. Palin's announcement came a day after Chris Christie, the governor of New Jersey, said he would not seek the GOP nomination in 2012. -- Written by Melinda Peer in New York.
