The Democratic Congressional Campaign Committee today announced radio spots aimed at 25 House Republicans they hope to unseat next fall to reclaim the majority.

The ads mostly focus on ethics questions, and will air in the districts of these Members:

GOP Reps. Rick Crawford (Ark.), Dan Lungren (Calif.), Jeff Denham (Calif.), Elton Gallegly (Calif.), Mary Bono Mack (Calif.), Scott Tipton (Colo.), Daniel Webster (Fla.), Vern Buchanan (Fla.), David Rivera (Fla.), Steve King (Iowa), Timothy Johnson (Ill.), Bobby Schilling (Ill.), Larry Bucshon (Ind.), Roscoe Bartlett (Md.), Dan Benishek (Mich.), Charles Bass (N.H.), Joe Heck (Nev.), Ann Marie Buerkle (N.Y.), Lou Barletta (Pa.), Charlie Dent (Pa.), Kristi Noem (S.D.), Francisco “Quico” Canseco (Texas), Sean Duffy (Wis.), Reid Ribble (Wis.) and David McKinley (W.Va.).

A GOP source said the ad buy totaled just less than $9,000 for all 25 districts. The DCCC refused to disclose the size of the ad buy but in a press release called it “aggressive and grass roots,” a signal it is not likely a large amount. The spots begin Monday. The DCCC said it would pair the campaign with phone banks, robocalls and Web ads in the districts.

The spot against Buchanan tells voters a watchdog group called him “one of the most corrupt Members of Congress.” Some of the ads are specific to Members’ troubles and some use general critiques the DCCC often lobs at the GOP.

“Congressman Jeff Denham is part of the problem in Washington.  Protect taxing breaks for billionaires instead of Medicare for seniors and jobs for us. Tell Congressman Denham to fight for California,” a narrator says in one spot.

“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 Steve Israel (N.Y.) said in a statement. “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.”
