This one from Time Magazine. The entire article is worth reading, since it chronicles a huge portion of her political experience ( > 50%).
Stein says that as mayor, Palin continued to inject religious beliefs into her policy at times. “She asked the library how she could go about banning books,” he says, because some voters thought they had inappropriate language in them. “The librarian was aghast.” That woman, Mary Ellen Baker, couldn’t be reached for comment, but news reports from the time show that Palin had threatened to fire Baker for not giving “full support” to the mayor.
I am searching for someone (not an SILive forums moron) to defend this woman- or even the McCain ticket anymore.
