The conservative outside group Crossroads GPS is out with a major new ad offensive against President Obama.

The new ad, “Basketball,” will air in 10 swing states. It’s a $9.7 million buy, part of the $25 million the group plans to spend this month.

Obama is also spending $25 million on ads in May.

The ad features a suburban mother who can’t retire and whose kids have moved back home. “I always loved watching the kids play basketball,” she says. ”I still do. Even though things have changed.”

The woman says she voted for Obama in 2008 “because he spoke so beautifully. He promised change. But things changed for the worse ... Now Obama wants more spending and taxes. That won’t fix things.”

Issue-advocacy groups like Crossroads GPS cannot advocate for candidates; the ad instead encourages viewers to “tell President Obama to cut the job-killing debt” and support the group’s New Majority Agenda.

The ad will start airing its 30- to 60-second versions Wednesday in Colorado, Florida, Iowa, Michigan, North Carolina, New Hampshire, Nevada, Ohio, Pennsylvania and Virginia.

Priorities USA Action, a pro-Obama super PAC, responded with another ad attacking former Massachusetts governor Mitt Romney’s Bain Capital record, “Loris and Ampad.” A former worker at American Pad & Paper, a company bought by Bain that went bankrupt, says Romney “made me sick.”

It's part of a $4 million Priorities buy in Colorado, Florida, Ohio, Pennsylvania and Virginia.

“[The] key feature of Karl Rove's ad is using actors to portray a fictional family,” Priorities spokesman Bill Burton said in a statement. “In our ads, we portray real life stories of Americans who were devastated by the decisions Mitt Romney made.”

Crossroads GPS and its sister group, the super PAC American Crossroads, were founded with help from former George W. Bush administration strategist Karl Rove.

The groups plan to spend $240 million this cycle against Obama. Right now the super PAC has been saving its money while Crossroads GPS, which does not have to disclose its donors, spends more freely.

Here’s a state-by-state breakdown of the “Basketball” ad buy:
