TIME magazine had this to say about the banning of books and Palin:

Time Article:

John Stein, former Alaskian mayor, "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.

Looks as though her own step-mother-in-law might not be voting for her, either.
