The National Republican Congressional Committee is targeting sophomore Rep. Joe Donnelly with its first independent expenditure ad. The ad tries to expose "the real Joe Donnelly" as a Congressman who supports the Democratic agenda and has ties to Speaker Nancy Pelosi (D-Calif.), not as the independent lawmaker he's portrayed himself in his own ads."In fact, Joe's taken $130,000 from Democratic leaders, over $30,000 from Nancy Pelosi alone, and now Joe Donnelly wants us to believe he's independent?" the narrator concludes incredulously.The ad started airing on Monday in the South Bend market and will run there for a week, according to NRCC spokesman Tom Erickson. The 30-second spot also mentions Donnelly's votes for health care reform, the financial bailout and the stimulus.Donnelly is in a tough race against state Rep. Jackie Walorski. This is far from the first ad in the district. Donnelly made waves last month when he aired an ad that tied Democratic leaders to the problems in Washington, D.C., and the Blue Dog has used his ads to paint himself as an independent. His current ad attacks Walorski for her support of the fair tax.
