What do religious people, in particular, Christian evangelicals, think of Sarah Palin's parenting skills?

ABC is reporting that the father of Bristol Palin’s baby, and her now former fiance, has broken up with her a couple of weeks ago.

A lot of evangelical Christians believe in abstinence. When their children have premarital sex, and conceive a baby, what do they think? Do they feel they have failed as parents? Or just that their kids made a mistake? DO they get angry, or just move on, considering themselves sinners who need forgiveness; what else is new?

Is Sarah Palin any good as a parent?
