NEW YORK (AP) -- A conservative-leaning independent group is launching a $10 million television ad campaign saying President Barack Obama has not lived up to the expectations voters had for him.

Crossroads GPS is running 30- and 60-second versions of the ad, titled "Basketball," in 10 swing states. The ad targets voters who backed Obama in 2008 but might vote against him this time.

The ad shows a young woman morphing into middle age as she worries about the economy, national debt and lack of jobs for her two adult children. She says she supported Obama but had become disillusioned, saying "he promised change, but things changed for the worse."

Crossroads GPS has ties to Karl Rove, President George W. Bush's longtime political strategist. The group is not required to disclose its donors.
