Sarah Palin said, when asked if she would/wanted to run for President, that "God show her any open doors, and point her to them" (paraphrasing).
It's abundantly clear that Sarah Palin is a complete moron and absolutely unqualified to be President. God may "work in mysterious ways" but proving someone is petty, stupid, and grossly incompetent is not his plan to get someone elected President of the United States.
Now, I am the first to concede that "God" (the concept, not the actual being) is making the Republican party dumber and dumber at a geometric rate. By 2012 the Republican base might be so incredibly stupid that they will deem Sarah Palin a viable presidentail candidate. But that is not opening a door for her, it's closing doors for all the people who are more qualified.
The only reason anyone in the continental United States even knows who Sarah Palin is is because John McCain had a really bad "senior moment" when picking his running mate.
Finally, I don't quite know what "God's grace" is, as it's a meaningless religious term. But whatever it is, Sarah Palin clearly does not have it. She's the most self-centered politician this country has ever seen. Jesus must be rolling around in his grave every time she mentions his name....
