"Education Week says Obama 'hasn't made a significant mark on education,'" an announcer says as the spot opens. "That he's 'elusive' on accountability. A 'staunch defender of the existing public school monopoly.'"
The announcer continues: "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."
Campaign spokesman Robert Gibbs told CBS News the legislation Obama supported provided information to children on what to watch for when with an adult they don't know, such as inappropriate advances or touching.
"It is shameful and downright perverse for the McCain campaign to use a bill that was written to protect young children from sexual predators as a recycled and discredited political attack against a father of two young girls – a position that his friend Mitt Romney also holds," Obama campaign spokesman Bill Burton said in a statement. "Last week, John McCain told Time magazine he couldn't define what honor was. Now we know why."
