Palin didn't cut Alaska's "special needs" education budget by 62% (she tripled it), she didn't ask for any books to be banned, she was never a member of the Alaskan Independence Party (though her husband was), she didn't endorse Patrick Buchanan for president in 2000 (she wore a Buchanan button as a courtesy when Buchanan visited Wasilla, but worked for Steve Forbes' campaign), and she hasn't tried to put creationism in schools.
UPDATE (September 16, 2008): Apparently one of the books that Palin had inquired about how to challenge and remove from the library was a book by a local Palmer, AK pastor named Rev. Howard Bess titled, Pastor, I am Gay. It does appear that there were some particular books that caught her attention which is why she made the inquiry.
UPDATE (September 16, 2008): Philip Munger of Wasilla says that Palin is definitely a young-earth creationist:
In June 1997, both Palin and I had responsibilities at the graduation ceremony of a small group of Wasilla area home schoolers. I directed the Mat-Su College Community Band, which played music, and she gave the commencement address. It was held at her church, the Wasilla Assembly of God.Surely there must be other witnesses besides Munger to her creationist views who can provide confirmation.
Palin had recently become Wasilla mayor, beating her earliest mentor, John Stein, the then-incumbent mayor. A large part of her campaign had been to enlist fundamentalist Christian groups, and invoke evangelical buzzwords into her talks and literature.
As the ceremony concluded, I bumped into her in a hall away from other people. I congratulated her on her victory, and took her aside to ask about her faith. Among other things, she declared that she was a young earth creationist, accepting both that the world was about 6,000-plus years old, and that humans and dinosaurs walked the earth at the same time.
I asked how she felt about the second coming and the end times. She responded that she fully believed that the signs of Jesus returning soon "during MY lifetime," were obvious. "I can see that, maybe you can't - but it guides me every day."
