Sen. Barack Obama said firmly that families are off-limits in the campaign for president, reacting to news that GOP running mate Sarah Palin's 17-year-old daughter is pregnant.
"Let me be as clear as possible," Obama said. "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 Gov. Palin's performance as governor or her potential performance as a vice president."
