(CNN) – Comedienne Tina Fey might be most well known for her 2008 portrayal of Sarah Palin on Saturday Night Live – an impersonation that, to the detriment of the McCain campaign, led many to confuse Fey with the real thing.
But now Fey is defending her role as Palin amid critics who say she unfairly exploited the Alaska governor.
"Some may argue that exploiting Governor Palin and her family helped bring attention to my low-rated TV show," writes Fey of 30 Rock, the NBC show that has struggled in the ratings despite critical acclaim.
Fey's comments appear in her new memoir, "Bossypants," an advance copy of which was obtained by USA Today.
"I am proud to say you are wrong," she continues. "My TV show still enjoys very low ratings. In fact, I think the Palin stuff may have hurt the TV show. Let's face it, between Alec Baldwin and me there is a certain fifty percent of the population who think we are pinko Commie monsters."
Despite appearing at Fey's side on Saturday Night Live shortly before the 2008 presidential election, Palin has since made clear she is no fan of the actress that many believe defined the former Alaska governor more than anyone else.
In a 2009 interview with conservative John Ziegler, Palin said of Fey, "I know that a lot of people are capitalizing on, oh I don't know, perhaps some exploiting that was done via me, my family, my administration – that's a little bit perplexing, but it also says a great deal about our society."
