Crossroads GPS, the Karl Rove-founded conservative group, is back with another ad in Virginia and nine other critical swing states attacking President Barack Obama on the economy.

The one-minute ad, titled “Basketball,” uses the story of a family’s struggles to go after the president on a number of fronts including health care, stimulus spending and nation’s mounting debt.

“I supported President Obama because he spoke so beautifully,” the female narrator says, noting that her adult children live at home because they can’t find jobs and adding that she cannot afford to retire. “He promised change. But things changed for the worse. Obama started spending like our credit cards have no limits.”

The ad is the $10 million centerpiece of a $25 million campaign by Crossroads GPS, and will air here and in Colorado, Florida, Iowa, Michigan, North Carolina, New Hampshire, Nevada, Ohio and Pennsylvania. It begins airing tomorrow in Virginia, where $1.5 million of air time has been purchased.

The ad urges citizens to support the “New Majority Agenda,” a list of legislation and principles supported by Crossroads.

The Democratic National Committee responded by noting that that more than 4.2 million private sector jobs have been created since Obama took office, claiming that the economic outlook continues to improve under his watch.

“Mitt Romney would undo that progress by bringing back the same policies that caused the economic crisis and weakened the middle class in the first place: budget-busting tax cuts for the wealthiest Americans that do nothing to grow our economy and letting Wall Street write its own rules,” the release said.
