Dirty words return to the usually staid Supreme Court Tuesday. For a second time in three years, the justices are hearing arguments about a Federal Communications Commission regulation adopted during the Bush administration that allows the agency to punish broadcasters with stiff fines for the fleeting use of vulgar language.

The central argument of Republican Mitt Romney's presidential campaign is that he understands how the economy works — thanks to his business background — in a way that President Obama does not.

Democrats have been challenging the former Massachusetts governor's claim that the private equity firm he founded helped to create more than 100,000 jobs. Now, some of Romney's Republican rivals are raising questions of their own.

The South Carolina primary is a week from Saturday. Before then, voters there can expect to be inundated with ads attacking Republican presidential candidate Mitt Romney and his role in Bain Capital.

"We made a $3.4 million ad buy in South Carolina, which is fairly significant," says Rick Tyler, senior adviser to the pro-Newt Gingrich SuperPAC Winning Our Future.

"Fairly significant" hardly does justice to the SuperPAC's plan.
