Sarah Palin's interview does not go quite as well as expected.
While she did present some positions consistent with Republican ideology, she lacked the general understanding of some other key points. Specifically, she had no understanding of what the "Bush Doctrine" in foreign policy, instead refusing to answer the question twice before going to a stock response. Additionally, Palin linked September 11th to Iraq instead of Al-Qaeda, a position that has thus far not been validated through facts or even accepted by the current Administration. She also purposefully skirted a question about whether she believed that the Iraq War was a "mission from God", turning to an Abraham Lincoln quote to deflect away from her own comments.
It is clear from this interview that Palin is not yet ready to be Vice President. While she herself might be proud of being a Washington outsider, her lack of experience or even knowledge of national politics and issues makes it impossible to say that she is ready to be a heartbeat away from the Presidency. Ultimately she showed that she was more like Dan Quayle as a VP nominee, and the fact that she accepted the nomination unquestioningly shows either hubris or a lack of ability to clearly evaluate herself.
