Palin said that Miss California Carrie Prejean has been the victim of a "liberal onslaught of malicious attacks." The governor added that the beauty pageant contestant had been attacked for expressing her opinions, something Palin called "despicable."
"Carrie and I spoke soon after the attacks started; I can relate as a liberal target myself," she wrote.
The Alaska governor, a former beauty pageant contestant herself, made no mention of the topless photos in her statement.
Prejean, who finished second in the Miss USA beauty pageant, has won the support of social conservatives thanks to her statement of opposition to same sex marriage and the ensuing controversy.
Topless photos emerged of Prejean in the wake of the contest, leading to debate over whether she should be stripped of her title. Pageant owner Donald Trump eventually decreed that the 22-year-old could keep her crown, in part because she is "very beautiful." Palin hailed the decision in her statement.
It also emerged that Prejean got breast implants shortly before the contest, and that beauty pageant officials had paid for them.
"What I find so remarkable is that these politically-motivated attacks fail to show that what Carrie and I believe is also what President Obama and Secretary Clinton believe -- marriage is between a man and a woman," Palin said in her statement. "Our Constitution protects us all -- not just those who agree with the far left."
