Today's ads include one targeting Republican candidate for Pennsylvania's 12th district Keith Rothfus for signing the Americans for Tax Reform "Taxpayer Protection Pledge," which the ad characterizes as protecting "tax breaks for companies that ship jobs overseas."

Another DCCC ad released today attacks Rep. Bill Johnson in Ohio's 06th District, and it's the group's first attack there. The ad accuses Johnson of voting to protect tax breaks for outsourcing, connecting that to his business career by pointing out Johnson shipped jobs overseas and received tax breaks.

Those, along with ads in Arizona, California, New York, Illinois and Texas launched this week, mark a barrage of attacks to launch the DCCC's general election campaign.
