17 year old should stay off limits, but not how the Democrat's policies would be better.
Obama is correct that Palin's 17 year old daughter should be off limits. We should not fault her or think anything bad about her.
The issues raised by a pregnant unwed 17 year old are within limits to discuss. The Democrats need to point out that their policies are much better for an unwed 17 year old who is pregannt. The Democrats would make sure that that mother and child have health care, that the child can get pre school education (head start), a higher education (college tuition tax credits for community service) and a fair shot at being the best possible person. The Republicans just say pull yourself up by your bootstraps.
Imagine that it was not a governor's 17 year old daughter who was pregnant, but a child of a working poor family. The Democrats would want that child to have the same opportunities, but the Republicans are indifferent.
No attack should be made upon the daughter who has really done nothing wrong, but the Democrats should use this opportunity to highlight how their policies are better for someone in this position.
