Frank Cornish has some thoughts about the issue:

If she [Sarah Palin] wants to be president, fine, it’s a Republic not a monarchy and anyone who wants to throw his or her hat in the ring is welcome to do so. They just need to raise money, get the supporters, convince the base of her party that if they nominate her then she will be able to push Obama out of the White House on a wave of popular support. But then, once she is in office she will actually need to do something constructive for the country. She will need to negotiate, and she will need to know what she is doing and what she is saying and she won’t be able to prepare for the negotiation session by putting a few phrases on her palm to remember that “Cutting taxes good.”
The President will not be able to sit at a table in Geneva, or a summit in Rejkjavik with the leader of a Muslim nation with crib notes that say “Islam is Terrorism.” The President will not be able to sit with the Secretary of Education and say “We need to teach more Bible in Science Class because” (reading palm) “Genesis is the literal word of God.”
