Should Bristol Palin's pregnancy be a matter of public interest?

The biggest story of the day behind Gustav was the pregnancy of the daughter of Sarah Palin, McCain’s VP choice. Obama said the following: “I have said before and I will repeat again, I think people’s families are off limits, and people’s children are especially off limits. This shouldn’t be part of our politics. It has no relevance to Governor Palin’s performance as governor, or her potential performance as a VP. And so I would strongly urge people to back off these kinds of stories.”

I want to know what Fluther thinks. Is this a private matter, or an important test of character for someone who could be a heartbeat away from the presidency? Should we care?
