(CNN) - Democrats will begin airing biting radio ads in the districts of 25 House Republicans Monday, claiming the targeted members of Congress are beholden to special interests and have questionable ethics.
The ads, produced and paid for by the Democratic Congressional Campaign Committee, were released to coincide with the one-year point to the 2012 election. Democrats hope to regain control of the House of Representatives next November.
The radio spots focus on Republicans the DCCC have identified as vulnerable in next year's election, and are part of a campaign called "Drive for 25," which will also incorporate phone calls to voters, internet advertising, and automated telephone calls.
Democrats would need to pick up 25 House seats currently held by Republicans to regain the majority of the House in 2012. Republicans currently hold a 242-193 majority in the House.
In a statement, the chairman of the DCCC said the 25 Republicans his group has singled out are vulnerable because of their ties to special interests.
"With one year to go until the election, the House Republicans' majority is in peril as it gets freezing cold back at home and Republicans face a chilly response to defending the indefensible," DCCC Chairman Rep. Steve Israel said. "House Republicans will be forced to defend protecting Big Oil and the ultra wealthy instead of protecting Medicare and creating jobs and defend their big ethics scandals too."
The ads, which will run in 15 different states, use specific items from the records of each House member. In many, incidents from past careers in business are highlighted.
An ad running against Rep. Vern Buchanan, R-Florida, claims the congressman's car dealership violated the law. A separate ad hitting Rep. Reid Ribble, R-Wisconsin says Ribble's company was fined for safety violations.
Other ads hone in on ethical questions, suggesting the members of Congress are indebted to special interest lobbies.
The ad running in the Arkansas district of Rep. Rick Crawford claims Crawford ensured tax loopholes for oil companies.
"Congressman Crawford is making sure that big oil companies keep their giant tax loopholes and the most wealthy keep their tax cuts - and hasn't done anything to create more jobs or help the middle class," the ad says.
The ad continues, "Congressman Crawford is listening to his special interest friends instead of fighting for us. That's just not right."
