altA Newsweek cover showing Sarah Palin in running shorts is "sexist," the former Alaska Governor said.

In a message on her Facebook page last night, Palin lamented that the magazine used a picture of her from a Runner's World photo shoot.

"The out-of-context Newsweek approach is sexist and oh-so-expected by now," Palin said.

She added: "If anyone can learn anything from it: it shows why you shouldn't judge a book by its cover, gender, or color of skin. The media will do anything to draw attention--even if out of context."

The accompanying article, by Evan Thomas, criticizes Palin's influence in the GOP.
