If Obama were to go tit for tat with McCain’s Education ad:

Announcer:
John McCain just put out an ad criticizing Barack Obama on sex education.

Play clip of McCain ad:
Obama’s one accomplishment? Legislation to teach ‘comprehensive sex education’ to kindergartners. Learning about sex before learning to read? Barack Obama. Wrong on education. Wrong for your family.

Announcer:
But here’s what John McCain didn’t tell you. This valuable legislation protects kindergartners from sexual predators, teaching them the difference between appropriate and inappropriate touching.
Do you want a candidate who protects your children, or who protects sexual predators?
John McCain. He’ll touch your children at night.
