King is attacked on a number of fronts, including what the ad characterizes as his votes to cut Pell Grants and for having taxpayers pay for his "luxury SUV." Another ad says Johnson's company outsourced jobs, and that he voted to make it easier for other U.S. companies to do the same.
Duffy faces a common attack in his ad: that he's out of touch, an accusation that riffs off of comments he made that he has a hard time paying his bills, despite his lawmaker's salary.
And though Rouzer isn't in office, the ad in his district obscures that fact, calling him a "lobbyist politician giving access to special interests and taking their campaign cash."
Each incumbent candidate targeted by the ads also appears on the DCCC's Red to Blue list, indicating Democrats believe these are races that, were they to win, could bring the party one step closer to the majority in the House.
