News today is that Palin's daughter Bristol is pregnant.
This will not affect the religious right's enthusiasm for Sarah Palin. McCain apparently knew about it before picking her, which for me raises my opinion of him.
Obama himself was conceived out of wedlock and has told his side to back off.
I seriously doubt his minions would do so. Thus it will be a test for him to see how low he will let his supporters go in pursuing criticism of Sarah Palin herself. What remains at play here are the independent women, men and families with teenage girls. My first impression is that they will sympathize with the Palins and despise those who will attack them.
