With congressional approval ratings at historic lows, Romney hopes to cast himself as a Washington outsider who can bring change to a party that has lost its way. In the ad, he tackles several problems that the party’s conservative base has with GOP lawmakers in Washington, including a lack of fiscal discipline, efforts to pass a comprehensive immigration bill and the ethics woes that have plagued Republicans.

“We can’t be like Democrats — a party of big spending,” Romney says in the spot. “We can’t pretend our borders are secure from illegal immigration. We can’t have ethical standards that are a punch line for Jay Leno.”

The ad will begin airing in New Hampshire Wednesday and in Iowa on Saturday.
